Categories: Exploits and vulnerabilities Categories: News Google has updated its Chrome Stable Channel to fix, among other things, an actively exploited vulnerability (Read more...) The post Update Chrome now! Google patches another actively exploited vulnerability appeared first on Malwarebytes Labs.

Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 117.0.5938.132 and libvpx 1.13.1 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Google on Wednesday rolled out fixes to address a new actively exploited zero-day in the Chrome browser. Tracked as CVE-2023-5217, the high-severity vulnerability has been described as a heap-based buffer overflow in the VP8 compression format in libvpx, a free software video codec library from Google and the Alliance for Open Media (AOMedia). Exploitation of such buffer overflow flaws can

Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.

During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing an attacker to write two NUL bytes, and cause a potentially exploitable crash. This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.
