CVE-2012-5153
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 V8 before 3.14.5.3, as used in Google Chrome before 24.0.1312.52, allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that triggers an out-of-bounds access to stack memory.
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 confidenceOut-of-bounds stack memory access vulnerability in Google V8 JavaScript engine versions before 3.14.5.3 (and Google Chrome before 24.0.1312.52). Attackers can trigger the flaw via crafted malicious JavaScript code, potentially achieving denial of service or unspecified code execution.

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.
-
Identify installed Google Chrome versionNavigate to chrome://version in the Chrome address bar or go to Help > About Google Chrome. Record the version number displayed.Affected if Version is 24.0.1312.51 or lower, or matches any of these specific versions: 24.0.1272.0, 24.0.1272.1, 24.0.1273.0, 24.0.1274.0, 24.0.1275.0, 24.0.1276.0, 24.0.1276.1, 24.0.1277.0, 24.0.1278.0, 24.0.1279.0, or 24.0.1280.0
-
Identify V8 JavaScript engine version in ChromeOpen the Chrome JavaScript console (F12 or Ctrl+Shift+J) and run: `console.log(navigator.userAgent)`. The V8 version typically appears in the user agent string after "Chrome/VERSION" (for example, V8 version 3.14.5.x would show in the full string). Alternatively, in the console run: `console.log(version)` if available.Affected if The V8 version number is lower than 3.14.5.3 (for example, 3.14.5.0, 3.14.4.x, or earlier)
-
Identify V8 version if embedded in a third-party applicationCheck the application documentation or about dialog for the bundled V8 version. Some applications expose V8 version via their internal JavaScript engine, or you may need to check the application's dependency manifest or binary version information.Affected if The embedded V8 version is lower than 3.14.5.3
You are affected if Google Chrome version is 24.0.1312.51 or earlier (including the specific 24.0.1272.0-24.0.1280.0 versions listed), or if the V8 JavaScript engine version is 3.14.5.2 or lower regardless of the Chrome version.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade V8 engine to version 3.14.5.3 or later, or upgrade affected Google Chrome installations to 24.0.1312.52 or later. If V8 is embedded in a custom application, rebuild with the patched V8 version.
