Update Chrome Now: Google Releases Patch for Actively Exploited Zero-Day Vulnerability

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

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 result in program crashes or execution of arbitrary code, impacting its availability and integrity.

Clément Lecigne of Google’s Threat Analysis Group (TAG) has been credited with discovering and reporting the flaw on September 25, 2023, with fellow researcher Maddie Stone noting on X (formerly Twitter) that it has been abused by a commercial spyware vendor to target high-risk individuals.

No additional details have been disclosed by the tech giant other than to acknowledge that it’s “aware that an exploit for CVE-2023-5217 exists in the wild.”

The latest discovery brings to five the number of zero-day vulnerabilities to Google Chrome for which patches have been released this year -

  • CVE-2023-2033 (CVSS score: 8.8) - Type confusion in V8
  • CVE-2023-2136 (CVSS score: 9.6) - Integer overflow in Skia
  • CVE-2023-3079 (CVSS score: 8.8) - Type confusion in V8
  • CVE-2023-4863 (CVSS score: 8.8) - Heap buffer overflow in WebP

The development comes as Google assigned a new CVE identifier, CVE-2023-5129, to the critical flaw in the libwebp image library – originally tracked as CVE-2023-4863 – that has come under active exploitation in the wild, considering its broad attack surface.

Users are recommended to upgrade to Chrome version 117.0.5938.132 for Windows, macOS, and Linux to mitigate potential threats. Users of Chromium-based browsers such as Microsoft Edge, Brave, Opera, and Vivaldi are also advised to apply the fixes as and when they become available.

Critical libwebp Vulnerability Under Active Exploitation - Gets Maximum CVSS Score

Google has assigned a new CVE identifier for a critical security flaw in the libwebp image library for rendering images in the WebP format that has come under active exploitation in the wild. Tracked as CVE-2023-5129, the issue has been given the maximum severity score of 10.0 on the CVSS rating system. It has been described as an issue rooted in the Huffman coding algorithm - With a specially

CVE-2023-5129

With a specially crafted WebP lossless file, libwebp may write data out of bounds to the heap. The ReadHuffmanCodes() function allocates the HuffmanCode buffer with a size that comes from an array of precomputed sizes: kTableSize. The color_cache_bits value defines which size to use. The kTableSize array only takes into account sizes for 8-bit first-level table lookups but not second-level table lookups. libwebp allows codes that are up to 15-bit (MAX_ALLOWED_CODE_LENGTH). When BuildHuffmanTable() attempts to fill the second-level tables it may write data out-of-bounds. The OOB write to the undersized array happens in ReplicateValue.
