CVE-2011-2858
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedGoogle Chrome before 14.0.835.163 does not properly handle triangle arrays, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceGoogle Chrome before 14.0.835.163 contains an out-of-bounds read vulnerability in its handling of triangle arrays used in WebGL or graphics rendering. An attacker can exploit this to cause a denial of service by reading memory outside the intended bounds via specially crafted triangle array data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Chrome versionNavigate to chrome://settings/help in the browser address bar, or run 'google-chrome --version' from the command lineAffected if Version displayed is less than 14.0.835.163 (e.g., 14.0.835.162 or any earlier version)
-
Verify WebGL is enabledNavigate to chrome://gpu/ in the address bar and review the WebGL status under the Graphics feature list, or visit a WebGL-enabled test websiteAffected if WebGL is enabled or hardware-accelerated and the Chrome version is below 14.0.835.163
-
Check hardware acceleration statusNavigate to chrome://settings and locate the 'Use hardware acceleration when available' setting under the Advanced section, or check chrome://gpu for hardware acceleration statusAffected if Hardware acceleration is enabled and the Chrome version is below 14.0.835.163
A user is affected if their Chrome version is below 14.0.835.163 and they have WebGL or hardware acceleration enabled, as the vulnerability exists in the triangle array handling during graphics rendering.
