CVE-2012-2831
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 · uneditedUse-after-free vulnerability in Google Chrome before 20.0.1132.43 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to SVG references.
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 confidenceUse-after-free vulnerability in Google Chrome's SVG reference handling allows remote attackers to cause denial of service or potentially achieve arbitrary code execution through specially crafted SVG content that exploits memory corruption after an object is freed.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Determine installed Chrome versionOpen Chrome and navigate to chrome://settings/help, or click Menu > Help > About Google Chrome. The version number is displayed on that page.Affected if The version listed is 20.0.1132.42 or lower, or specifically any version from 20.0.1132.0 through 20.0.1132.42
-
Confirm Chrome is the affected browserVerify the browser is Google Chrome and not Chromium or another Chromium-based browser, as this CVE specifically targets Google Chrome.Affected if The browser is Google Chrome and the version falls within the affected range
-
Verify SVG content can be processedThe vulnerability exists in SVG reference handling. Any SVG content processed by Chrome (including embedded SVG in web pages, SVG files opened directly, or SVG in extensions) would trigger the vulnerable code path.Affected if Chrome processes SVG content and the installed version is within the affected range
A user is affected if they are running Google Chrome version 20.0.1132.42 or any version from 20.0.1132.0 through 20.0.1132.42 and the browser processes SVG content.

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 dataUpdate Google Chrome to version 20.0.1132.43 or later to patch the use-after-free vulnerability in SVG reference handling. Organizations should deploy the update via their patch management systems and verify successful remediation.
