Joe Vennix of Apple security has found another significant vulnerability in sudo utility that under a specific configuration could allow low privileged users or malicious programs to execute arbitrary commands with administrative ('root') privileges on Linux or macOS systems. Sudo is one of the most important, powerful, and commonly used utilities that comes as a core command pre-installed on macOS and almost every UNIX or Linux-based operating system. Sudo has been designed to let users run apps or commands with the privileges of a different user without switching environments. Sudo Vulnerability (CVE-2019-18634) The newly discovered privilege escalation vulnerability, tracked as CVE-2019-18634 , in question stems from a stack-based buffer overflow issue that resides in Sudo versions before 1.8.26. According to Vennix, the flaw can only be exploited when the " pwfeedback " option is enabled in the sudoers configuration file, a feature that provides visua

Besides rewarding ethical hackers from its pocket for responsibly reporting vulnerabilities in third-party open-source projects, Google today announced financial support for open source developers to help them arrange additional resources, prioritizing the security of their products. The initiative, called " Patch Rewards Program ," was launched nearly 6 years ago, under which Google rewards hackers for reporting severe flaws in many widely used open source software, including OpenSSH, OpenSSL, Linux kernel, Apache, Nginx, jQuery, and OpenVPN. So far, Google has paid hundreds of thousands of dollars as bounty to hackers across the world who helped improve the overall security of many crucial open source software and technologies that power the Internet, operating systems, and networks. The company has now also decided to motivate volunteer work done by the open source community by providing upfront financial help to project teams, using which they can acquire addition

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

Are you using an Android device? Beware! You should be more careful while playing a video on your smartphone—downloaded anywhere from the Internet or received through email. That's because, a specially crafted innocuous-looking video file can compromise your Android smartphone—thanks to a critical remote code execution vulnerability that affects over 1 billion devices running Android OS between version 7.0 and 9.0 (Nougat, Oreo, or Pie). The critical RCE vulnerability (CVE-2019-2107) in question resides in the Android media framework, which if exploited, could allow a remote attacker to execute arbitrary code on a targeted device. To gain full control of the device, all an attacker needs to do is tricking the user into playing a specially crafted video file with Android's native video player application. Though Google already released a patch earlier this month to address this vulnerability, apparently millions of Android devices are still waiting for the latest A

Microsoft today released its monthly batch of software security updates for the July month to patch a total of 77 vulnerabilities, 14 are rated Critical, 62 are Important, and 1 is rated Moderate in severity. The July 2019 security updates include patches for various supported versions of Windows operating systems and other Microsoft products, including Internet Explorer, Edge, Office, Azure DevOps, Open Source Software, .NET Framework, Azure, SQL Server, ASP.NET, Visual Studio, and Exchange Server. Details of 6 security vulnerabilities, all rated important, were made public before a patch was released, none of which were found being exploited in the wild. However, two new privilege escalation vulnerabilities, one affects all supported versions of the Windows operating system, and the other affects Windows 7 and Server 2008, have been reported as being actively exploited in the wild. Both actively exploited vulnerabilities lead to elevation of privilege, one (CVE-2019-1132)

Update (22 June 2019)  — More technical details and proof-of-concept for the OutLook for Android vulnerability has been released that we have covered in a separate article here. Microsoft today released an updated version of its "Outlook for Android" that patches an important security vulnerability in the popular email app that is currently being used over 100 million users. According to an advisory , Outlook app with versions before 3.0.88 for Android contains a stored cross-site scripting vulnerability ( CVE-2019-1105 ) in the way the app parses incoming email messages. If exploited, remote attackers can execute malicious in-app client-side code on the targeted devices just by sending them emails with a specially crafted message. "The attacker who successfully exploited this vulnerability could then perform cross-site scripting attacks on the affected systems and run scripts in the security context of the current user." According to Microsoft, the fl

In recent years, we have seen how hackers prey on those too lazy or ignorant to install security patches, which, if applied on time, would have prevented some devastating cyber attacks and data breaches that happened in major organisations. The United States Department of Homeland Security (DHS) has ordered government agencies to more swiftly plug the critical security vulnerabilities found on their networks within 15 calendar days since the initial detection, a reduction from 30 days. DHS's Cybersecurity and Infrastructure Security Agency (CISA) this week issued a new Binding Operational Directive (BOD) 19-02 instructing federal agencies and departments to address "critical" rated vulnerabilities within 15 days and "high" severity flaws within 30 days of initial detection. The countdown to patch a security vulnerability will start when it was initially detected during CISA's weekly Cyber Hygiene vulnerability scanning, rather than it was the firs

Adobe users would feel lighter this month, as Adobe has released patches for just two security vulnerability in its March Security Update. The company today released its monthly security updates to address two critical arbitrary code execution vulnerabilities—one in Adobe Photoshop CC and another in Adobe Digital Editions. Upon successful exploitation, both critical vulnerabilities could allow an attacker to achieve arbitrary code execution in the context of the current user and take control of an affected system. However, the good news is that the company found no evidence of any exploits in the wild for these security issues, Adobe said. The vulnerability in Adobe Photoshop CC , discovered by Trend Micro Zero Day Initiative and assigned CVE-2019-7094, is a heap corruption issue which affects Photoshop CC 19.1.7 and earlier 19.x versions as well as Photoshop CC 20.0.2 and earlier 20.x versions for Microsoft Windows and Apple macOS operating systems. Users are recommended

I hope you had biggest, happiest and craziest New Year celebration, but now it's time to come back at work and immediately update your systems to patch new security flaws that could exploit your computer just by opening a PDF file. Adobe has issued an out-of-band security update to patch two critical vulnerabilities in the company's Acrobat and Reader for both the Windows and macOS operating systems. Though the San Jose, California-based software company did not give details about the vulnerabilities, it did classify the security flaws as critical since they allow privilege escalation and arbitrary code execution in the context of the current user. Both the vulnerabilities were reported to Adobe by security researchers--Abdul-Aziz Hariri and Sebastian Apelt—from Trend Micro's Zero Day Initiative (ZDI). Critical Adobe Acrobat and Reader Vulnerabilities The first vulnerability, reported by Apelt and identified as CVE-2018-16011, is a use-after-free bug that can lead

Adobe is closing out this year with its December Patch Tuesday update to address a massive number of security vulnerabilities for just its two PDF apps—more than double the number of what Microsoft patched this month for its several products. Adobe today released patches for 87 vulnerabilities affecting its Acrobat and Reader software products for both macOS and Windows operating systems, of which 39 are rated as critical and 48 important in severity. The security update comes less than a week after Adobe released patches for a critical zero-day vulnerability (CVE-2018-15982) in Flash Player that was actively being exploited in a targeted attack targeting a Russian state health care institution. The critical vulnerabilities addressed today in Acrobat and Reader include three heap-overflow bugs, five out-of-bounds write flaws, two untrusted pointer dereference issues, two buffer errors, and 24 use-after-free bugs. Upon successful exploitation, all of the above critical vulner

It's time to gear up your systems and software for the latest July 2018 Microsoft security patch updates. Microsoft today released security patch updates for 53 vulnerabilities, affecting Windows, Internet Explorer (IE), Edge, ChakraCore, .NET Framework, ASP.NET, PowerShell, Visual Studio, and Microsoft Office and Office Services, and Adobe Flash Player. Out of 53 vulnerabilities, 17 are rated critical, 34 important, one moderate and one as low in severity. This month there is no critical vulnerability patched in Microsoft Windows operating system and surprisingly, none of the flaw patched by the tech giant this month is listed as publicly known or under active attack. Critical Flaws Patched In Microsoft Products Most of the critical issues are memory corruption flaws in IE, Edge browser and Chakra scripting engine, which if successfully exploited, could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system in the context of the cur

Adobe has released security patches for a total 112 vulnerabilities in its products, most of which have a higher risk of being exploited. The vulnerabilities addressed in this month's patch Tuesday affect Adobe Flash Player, Adobe Experience Manager, Adobe Connect, Adobe Acrobat, and Reader. None of the security vulnerabilities patched this month were either publicly disclosed or found being actively exploited in the wild. Adobe Flash Player (For Desktops and Browsers) Security updates include patches for two vulnerabilities in Adobe Flash Player for various platforms and application, as listed below. One of which has been rated critical (CVE-2018-5007), and successful exploitation of this "type confusion" flaw could allow an attacker to execute arbitrary code on the targeted system in the context of the current user. This flaw was discovered and reported to Adobe by willJ of Tencent PC Manager working with Trend Micro's Zero Day Initiative. Withou

Adobe has just released new versions of its Acrobat DC, Reader and Photoshop CC for Windows and macOS users that patch 48 vulnerabilities in its software. A total of 47 vulnerabilities affect Adobe Acrobat and Reader applications, and one critical remote code execution flaw has been patched in Adobe Photoshop CC. Out of 47, Adobe Acrobat and Reader affect with 24 critical vulnerabilities —categorized as Double Free, Heap Overflow, Use-after-free, Out-of-bounds write, Type Confusion, and Untrusted pointer dereference—which if exploited, could allow arbitrary code execution in the context of the targeted user. Rest of the 23 flaws, including Security Bypass, Out-of-bounds read, Memory Corruption, NTLM SSO hash theft, and HTTP POST newline injection via XFA submission, are marked as important and can lead to information disclosure or security bypass. The above-listed vulnerabilities impact the Windows and macOS versions of Acrobat DC (Consumer and Classic 2015), Acrobat Rea

Since hackers have started exploiting two recently disclosed unpatched critical vulnerabilities found in GPON home routers, security researchers have now released an unofficial patch to help millions of affected users left vulnerable by their device manufacturer. Last week, researchers at vpnMentor disclosed details of—an authentication bypass (CVE-2018-10561) and a root-remote code execution vulnerability (CVE-2018-10562)—in many models of Gigabit-capable Passive Optical Network (GPON) routers manufacturer by South Korea-based DASAN Zhone Solutions. If exploited, the first vulnerability lets an attacker easily bypass the login authentication page just by appending ?images/ to the URL in the browser's address bar. However, when coupled with the second flaw that allows command injection, unauthenticated attackers can remotely execute malicious commands on the affected device and modified DNS settings, eventually allowing them to take full control of the device remotely.

Just a few days prior to its monthly patch release, Microsoft released an emergency patch for a critical vulnerability in the Windows Host Compute Service Shim (hcsshim) library that could allow remote attackers to run malicious code on Windows computers. Windows Host Compute Service Shim (hcsshim) is an open source library that helps "Docker for Windows" execute Windows Server containers using a low-level container management API in Hyper-V. Discovered by Swiss developer and security researcher Michael Hanselmann , the critical vulnerability (tracked as CVE-2018-8115) is the result of the failure of the hcsshim library to properly validate input when importing a Docker container image. This, in turn, allows an attacker to remotely execute arbitrary code on the Windows host operating system, eventually letting the attacker create, remove, and replace files on the target host. As Hanselmann explained  in his personal blog, "Importing a Docker container image or

Earlier this month, Oracle patched a highly critical Java deserialization remote code execution vulnerability in its WebLogic Server component of Fusion Middleware that could allow attackers to easily gain complete control of a vulnerable server. However, a security researcher, who operates through the Twitter handle @pyn3rd and claims to be part of the Alibaba security team, has now found a way using which attackers can bypass the security patch and exploit the WebLogic vulnerability once again. WebLogic Server acts as a middle layer between the front end user interface and the backend database of a multi-tier enterprise application. It provides a complete set of services for all components and handles details of the application behavior automatically. Initially discovered in November last year by Liao Xinxi of NSFOCUS security team, the Oracle WebLogic Server flaw (CVE-2018-2628) can be exploited with network access over TCP port 7001. If exploited successfully, the fl

Only a few hours after the Drupal team releases latest updates to fix a new remote code execution flaw in its content management system software, hackers have already started exploiting the vulnerability in the wild. Announced yesterday, the newly discovered vulnerability ( CVE-2018-7602 ) affects Drupal 7 and 8 core and allows remote attackers to achieve exactly same what previously discovered Drupalgeddon2 (CVE-2018-7600) flaw allowed—complete take over of affected websites. Although Drupal team has not released any technical details of the vulnerability to prevent immediate exploitation, two individual hackers have revealed some details, along with a proof-of-concept exploit just a few hours after the patch release. If you have been actively reading every latest story on The Hacker News, you must be aware of how the release of Drupalgeddon2 PoC exploit derived much attention, which eventually allowed attackers actively hijack websites and spread cryptocurrency miners , b

Damn! You have to update your Drupal websites. Yes, of course once again—literally it's the third time in last 30 days. As notified in advance two days back, Drupal has now released new versions of its software to patch yet another critical remote code execution (RCE) vulnerability, affecting its Drupal 7 and 8 core. Drupal is a popular open-source content management system software that powers millions of websites, and unfortunately, the CMS has been under active attacks since after the disclosure of a highly critical remote code execution vulnerability. The new vulnerability was discovered while exploring the previously disclosed RCE vulnerability, dubbed Drupalgeddon2 (CVE-2018-7600) that was patched on March 28, forcing the Drupal team to release this follow-up patch update. According to a new advisory released by the team, the new remote code execution vulnerability (CVE-2018-7602) could also allow attackers to take over vulnerable websites completely. How to Pa

Microsoft's Patch Tuesday for this month falls the day before the most romantic day of the year. Yes, it's Valentine's, and the tech giant has released its monthly security update for February 2018, addressing a total of 50 CVE-listed vulnerabilities in its Windows operating system, Microsoft Office, web browsers and other products. Fourteen of the security updates are listed as critical, 34 are rated as important, and 2 of them are rated as moderate in severity. The critical update patches serious security flaws in Edge browser and Outlook client, an RCE in Windows' StructuredQuery component, and several memory corruption bugs in the scripting engines used by Edge and Internet Explorer. Critical Microsoft Outlook Vulnerability One of the most severe bugs includes a memory corruption vulnerability ( CVE-2018-0852 ) in Microsoft Outlook, which can be exploited to achieve remote code execution on the targeted machines. In order to trigger the vulnerability

WordPress administrators are once again in trouble. WordPress version 4.9.3 was released earlier this week with patches for a total 34 vulnerabilities, but unfortunately, the new version broke the automatic update mechanism for millions of WordPress websites. WordPress team has now issued a new maintenance update, WordPress 4.9.4 , to patch this severe bug, which WordPress admins have to install manually. According to security site WordFence , when WordPress CMS tries to determine whether the site needs to install an updated version, if available, a PHP error interrupts the auto-update process. If not updated manually to the latest 4.9.4 version, the bug would leave your website on WordPress 4.9.3 forever, leaving it vulnerable to future security issues. Here's what WordPress lead developer Dion Hulse explained about the bug: "#43103-core aimed to reduce the number of API calls which get made when the auto-update cron task is run. Unfortunately, due to human e

After leaving million of devices at risk of hacking and then rolling out broken patches, Intel has now released a new batch of security patches only for its Skylake processors to address one of the Spectre vulnerabilities (Variant 2). For those unaware, Spectre ( Variant 1, Variant 2 ) and Meltdown ( Variant 3 ) are security flaws disclosed by researchers earlier last month in processors from Intel, ARM, and AMD, leaving nearly every PC, server, and mobile phone on the planet vulnerable to data theft. Shortly after the researchers disclosed the Spectre and Meltdown exploits , Intel started releasing microcode patches for its systems running Broadwell, Haswell, Skylake, Kaby Lake, and Coffee Lake processors. However, later the chip maker rollbacked the firmware updates and had to tell users to stop using an earlier update due to users complaining of frequent reboots and other unpredictable system behavior after installing patches. Although it should be a bit quicker, Intel i
