Attention readers, if you are using Chrome on your Windows, Mac, and Linux computers, you need to update your web browsing software immediately to the latest version Google released earlier today. With the release of Chrome 78.0.3904.87, Google is warning billions of users to install an urgent software update immediately to patch two high severity vulnerabilities, one of which attackers are actively exploiting in the wild to hijack computers. Without revealing technical details of the vulnerability, the Chrome security team only says that both issues are use-after-free vulnerabilities, one affecting Chrome's audio component ( CVE-2019-13720 ) while the other resides in the PDFium ( CVE-2019-13721 ) library. The use-after-free vulnerability is a class of memory corruption issues that allows corruption or modification of data in the memory, enabling an unprivileged user to escalate privileges on an affected system or software. Thus, both flaws could enable remote attackers...

Google has released an urgent software update for its Chrome web browser and is urging Windows, Mac, and Linux users to upgrade the application to the latest available version immediately. Started rolling out to users worldwide this Wednesday, the Chrome 77.0.3865.90 version contains security patches for 1 critical and 3 high-risk security vulnerabilities, the most severe of which could allow remote hackers to take control of an affected system. Google has decided to keep details of all four vulnerabilities secret for a few more days in order to prevent hackers from exploiting them and give users enough time to install the Chrome update. For now, Chrome security team has only revealed that all four vulnerabilities are use-after-free issues in different components of the web browser, as mentioned below, the critical of which could lead to remote code execution attacks. The use-after-free vulnerability is a class of memory corruption issue that allows corruption or modificat...

French security firm VUPEN Say New Bugs Can Bypass Google Chrome Sandbox ! Researchers at the French security firm VUPEN say that they have discovered several new vulnerabilities in Google Chrome that enable them to bypass the browser's sandbox, as well as ASLR and DEP and run arbitrary code on a vulnerable machine. The company said that they are not going to disclose the details of the bugs right now, but that they have shared information on them with some of their government customers through its customer program. The vulnerabilities are present in the latest version of Chrome running on Windows 7, VUPEN said. VUPEN published a video (  https://www.vupen.com/demos / ) that demonstrates an attack that exploits the Chrome vulnerabilities, although there is no further clues about the bugs themselves. "The exploit shown in this video is one of the most sophisticated codes we have seen and created so far as it bypasses all security features including ASLR/DEP/Sandbox, it...

Microsoft discloses vulnerabilities in Chrome and Opera Microsoft has issued two advisories on Chrome and Opera, detailing remote code execution and information disclosure vulnerabilities. The disclosure is the result of the Microsoft Vulnerability Research (MSVR) system going live, which is one of the core items within their Coordinated Vulnerability Disclosure (CVD) program. On Tuesday, Microsoft issued an MSRV Advisory related to use-after-free memory errors in Google's Chrome, which, if exploited, would have triggered a crash and allowed remote code execution in the browsers sandbox. "When attempting to parse specially crafted Web content, Google Chrome references memory that has been freed. An attacker could exploit the vulnerability to cause the browser to become unresponsive and/or exit unexpectedly, allowing an attacker to run arbitrary code within the Google Chrome Sandbox," the advisory explains. Google has addressed the issue in a patch delivered last September. Vers...

Google has announced support for what's called a  V8 Sandbox  in the Chrome web browser in an effort to address memory corruption issues. The sandbox, according to V8 security technical lead Samuel Groß,  aims  to prevent "memory corruption in V8 from spreading within the host process." The search behemoth has  described  V8 Sandbox as a lightweight, in-process sandbox for the JavaScript and WebAssembly engine that's designed to mitigate common V8 vulnerabilities. The idea is to limit the impact of V8 vulnerabilities by restricting the code executed by V8 to a subset of the process' virtual address space ("the sandbox") and isolating it from the rest of the process. Shortcomings affecting V8 have accounted for a significant chunk of the zero-day vulnerabilities that Google has  addressed  between  2021  and  2023 , with as many as 16 security flaws discovered over the time period. "The sandbox assumes that an attacker can arb...

Google on Thursday patched six vulnerabilities in Chrome, and as usual, silently updated users' copies of the browser. The update to Chrome 10.0.648.204 also included two more blacklisted SSL certificates that may be related to last week's theft of nine digital certificates from a Comodo reseller. All six bugs were rated "high," Google's second-most-serious ranking in its threat scoring system. Of the half-dozen bugs, two were "use after free" flaws -- a type of memory management bug that can be exploited to inject attack code -- while a second pair were pegged by Google as "stale pointer" vulnerabilities, another kind of memory allocation flaw. As is Google's practice, the company locked down its bug-tracking database, blocking access to the technical details of the patched vulnerabilities. Google usually unlocks the bug entries several weeks, sometimes months later, to give users time to update before the information goes public. G...

It was, for example, possible to crash the browser using JavaScript dialogs and SVG files, or to use the address bar for URL spoofing. Also fixed is an integer overflow when handling text areas. As ever, Google is keeping full details of the vulnerabilities under wraps until the bulk of users have switched to the new version. Google's rewards programme pays discoverers of vulnerabilities up to $1,000. Google paid out a total of $14,000 for this particular update. In total, its security bug bounty programme has now paid out more than $100,000. Chrome 9.0.597.107 is available to download for Windows, Mac OS X and Linux from google.com/chrome. Users who currently have Chrome installed can use the built-in update function by clicking To...

After enabling ' Site Isolation ' security feature in Chrome for desktops last year, Google has now finally introduced 'the extra line of defence' for Android smartphone users surfing the Internet over the Chrome web browser. In brief, Site Isolation is a security feature that adds an additional boundary between websites by ensuring that pages from different sites end up in different sandboxed processes in the browser. Since each site in the browser gets its own isolated process, in case of a browser flaw or Spectre like side-channel vulnerability, the feature makes it harder for attackers or malicious websites to access or steal cross-site data of your accounts on other websites. Site Isolation helps protect many types of sensitive data, including authentication cookies, stored passwords, network data, stored permissions, as well as cross-origin messaging that help sites securely pass messages across domains. The feature gained attention in January 2018, ...

Google has finally rolled out the latest version of its popular web browser, i.e. Chrome 42 for Windows, Mac, and Linux users that now lets websites send you alerts, no matter your browser is open or not.

The latest version of Chrome comes with fixes for 45 security vulnerabilities in the web browser, reported by different security researchers [listed below]. Let's know about the Major updates : Major updates and significant improvements for Chrome version 42 includes: Advanced Push API and Notifications API Disabled Oracle's Java plugin by default as well as other extensions that use NPAPI Patched 45 security bugs and paid out more than $21,000 Push API : Google includes Push API in its web browser for the first time. Push API, when combined with the new notifications API, allows websites to push notifications to you through y...

Google on Tuesday rolled out fixes for six security issues in its Chrome web browser, including one that it said has been exploited in the wild. The high-severity vulnerability in question is CVE-2025-6558 (CVSS score: 8.8), which has been described as an incorrect validation of untrusted input in the browser's ANGLE and GPU components. "Insufficient validation of untrusted input in ANGLE and GPU in Google Chrome prior to 138.0.7204.157 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page," according to the description of the flaw from the NIST's National Vulnerability Database (NVD). ANGLE, short for "Almost Native Graphics Layer Engine," acts as a translation layer between Chrome's rendering engine and device-specific graphics drivers. Vulnerabilities in the module can let attackers escape Chrome's sandbox by abusing low-level GPU operations that browsers usually keep isolated, making this a rare but powerful path...

With its latest and last Patch Tuesday for 2019, Microsoft is warning billions of its users of a new Windows zero-day vulnerability that attackers are actively exploiting in the wild in combination with a Chrome exploit to take remote control over vulnerable computers. Microsoft's December security updates include patches for a total of 36 vulnerabilities, where 7 are critical, 27 important, 1 moderate, and one is low in severity—brief information on which you can find later in this article. Tracked as CVE-2019-1458 and rated as Important, the newly patched zero-day Win32k privilege escalation vulnerability, reported by Kaspersky, was used in Operation WizardOpium attacks to gain higher privileges on targeted systems by escaping the Chrome sandbox. Although Google addressed the flaw in Chrome 78.0.3904.87 with the release of an emergency update last month after Kaspersky disclosed it to the tech giant, hackers are still targeting users who are using vulnerable versions of th...

Google will pay $ 20,000 for the first scientist who succeeds in its Chrome browser to exploit this year's competition Pwn2Own piracy. The price is the largest ever to face the annual challenge, which begins for the fifth time in the CanSecWest security conference in Vancouver, British Columbia, March 9. In Pwn2Own this year, researchers sky exploits against machines running Windows 7 or Mac OS X, as they try to download Microsoft Internet Explorer, Mozilla Firefox, Apple Safari and Chrome. The researchers first to hack IE, Firefox and Safari will receive $ 15,000 and the computer running the browser. Prices are $ 5,000 higher than those given for the use of browsers in the last contest Pwn2Own, and three times the 2009 price. "We've raised the bar this time and the total allocated to cash prices rose to a whopping $ 125,000," said Aaron Portnoy, director of HP TippingPoint Security Research Team. TippingPoint, which is once again sponsoring Pwn2Own, set th...

Yet Another Google Chrome Sandbox Critical Exploit by Turkish security experts Turkish security experts from Arf Iskenderun Technologies, finds the new vulnerability open in Google Chrome 17.0.963.78 , same risk working on new update 17.0.963.79 and bypass Chrome SandBox. Last week,  Vupen Security reports that it has officially "pwned" Google Chrome's sandbox. Vupen hacked Chrome 17.0.963.66 update. But, Turkish security experts claim that they hacked Chrome Sandbox after Vupen and This vulnerability is critical for Chrome.  A sandbox is security mechanism used to run an application in a restricted environment. If an attacker is able to exploit the browser in a way that lets him run arbitrary code on the machine, the sandbox would help prevent this code from causing damage to the system. The sandbox would also help prevent this exploit from modifying and even reading your files or any information on the system. Maiden says th...

Google has by default enabled a security feature called "Site Isolation" in its web browser with the release of Chrome 67 for all desktop users to help them protect against many online threats, including Spectre and Meltdown attack . Site Isolation is a feature of the Google Chrome web browser that adds an additional security boundary between websites by ensuring that different sites are always put into separate processes, isolated from each other. Since each site in the browser gets its own sandboxed process, the feature makes it harder for untrusted websites to access or steal information of your accounts on other websites. In January this year when Google Project Zero researchers disclosed details of Spectre and Meltdown CPU vulnerabilities, the tech giant recommended Chrome desktop users to manually turn on Site Isolation feature on their devices to mitigate speculative side-channel attacks. "Even if a Spectre attack were to occur in a malicious web page, ...

Details have emerged about a recently patched critical remote code execution vulnerability in the V8 JavaScript and WebAssembly engine used in Google Chrome and Chromium-based browsers. The issue relates to a case of use-after-free in the instruction optimization component, successful exploitation of which could "allow an attacker to execute arbitrary code in the context of the browser." The flaw, which  was identified  in the Dev channel version of Chrome 101, was reported to Google by Weibo Wang, a security researcher at Singapore cybersecurity company  Numen Cyber Technology  and has since been quietly fixed by the company. "This vulnerability occurs in the instruction selection stage, where the wrong instruction has been selected and resulting in memory access exception," Wang said . Use-after-free flaws  occur  when previous-freed memory is accessed, inducing undefined behavior and causing a program to crash, use corrupted data, or even achieve e...
