Adobe Patches Critical Bugs Affecting Media Encoder and After Effects

February 20, 2020Wang Wei
Adobe today released out-of-band software updates for After Effects and Media Encoder applications that patch a total of two new critical vulnerabilities. Both critical vulnerabilities exist due to out-of-bounds write memory corruption issues and can be exploited to execute arbitrary code on targeted systems by tricking victims into opening a specially crafted file using the affected software. The bug ( CVE-2020-3765 ) in Adobe After Effects, an application for creating motion graphics and special effects used in the video, was discovered by security researcher Matt Powell and reported to Adobe via Trend Micro Zero Day Initiative project. Whereas, the second issue ( CVE-2020-3764 ) affecting Adobe Media Encoder, software for encoding and compressing audio or video files, was discovered by Canadian security researcher Francis Provencher. None of the security vulnerabilities fixed in this batch of Adobe updates were publicly disclosed or found being exploited in the wild, as th

Sudo Bug Lets Non-Privileged Linux and macOS Users Run Commands as Root

February 03, 2020Mohit Kumar
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

Your Android Phone Can Get Hacked Just By Playing This Video

July 25, 2019Wang Wei
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

DHS Orders Federal Agencies to Patch Critical Flaws Within 15 Days

May 01, 2019Mohit Kumar
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

A Simple Tool Released to Protect Dasan GPON Routers from Remote Hacking

May 08, 2018Swati Khandelwal
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.
Microsoft Issues Emergency Patch For Critical Flaw In Windows Containers

Microsoft Issues Emergency Patch For Critical Flaw In Windows Containers

May 03, 2018Swati Khandelwal
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
Faulty Patch for Oracle WebLogic Flaw Opens Updated Servers to Hackers Again

Faulty Patch for Oracle WebLogic Flaw Opens Updated Servers to Hackers Again

April 30, 2018Swati Khandelwal
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
