CVE-2012-2893
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 · uneditedDouble free vulnerability in libxslt, as used in Google Chrome before 22.0.1229.79, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to XSL transforms.
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 · moderate confidenceA double-free vulnerability in libxslt allows remote attackers to cause denial of service or potentially achieve arbitrary code execution by submitting specially crafted XSL transform documents that trigger incorrect memory management during stylesheet processing.

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 Google Chrome versionNavigate to chrome://settings/help or use 'Chrome --version' from command line to see the installed version numberAffected if Version is 22.0.1229.78 or lower, OR matches any of the specific vulnerable versions (22.0.1229.0 through 22.0.1229.11)
-
Identify exact version stringLook at the full version number displayed (for example, 22.0.1229.78) and compare to the affected versions listAffected if Version string exactly matches 22.0.1229.x where x is 0-78 inclusive, or matches any of the explicitly listed versions
-
Verify XSL transform capability is in useCheck if Chrome is processing or can process XSLT content - this is built into libxslt which Chrome uses for XML stylesheet transformationsAffected if The double-free occurs during XSL stylesheet processing, but the vulnerable code exists in any Chrome installation of the affected versions regardless of immediate use
User is affected if Google Chrome version is 22.0.1229.78 or lower, or matches any of the specific vulnerable 22.0.1229.x versions listed in the affected products.

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 to Google Chrome 22.0.1229.79 or later; for other applications using libxslt, update to the patched libxslt version that addresses the double-free condition in XSL transform processing.
