CVE-2011-3003
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 · uneditedMozilla Firefox before 7.0 and SeaMonkey before 2.4 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an unspecified WebGL test case that triggers a memory-allocation error and a resulting out-of-bounds write operation.
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 confidenceMemory corruption vulnerability in WebGL implementation where an unspecified WebGL test case triggers a memory-allocation error leading to out-of-bounds write operations, potentially allowing arbitrary code execution or denial of service via application crash.

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 Mozilla productCheck if Mozilla Firefox or Mozilla Seamonkey is installed by looking at the application name in Add/Remove Programs, the program files directory, or running 'firefox -v' or 'seamonkey -v' from the command lineAffected if Neither Firefox nor Seamonkey is installed (not affected)
-
Check Firefox versionRun 'firefox -v' from command line or look at Help > About Firefox to find the exact version numberAffected if Version is below 7.0 (for example, 6.0.1, 6.0, 5.x, etc.)
-
Check Seamonkey versionRun 'seamonkey -v' from command line or look at Help > About Seamonkey to find the exact version numberAffected if Version is below 2.4 (for example, 2.3, 2.2, 2.1, etc.)
-
Verify WebGL is enabledIn Firefox, type 'about:config' in the address bar, search for 'webgl', and check if webgl.enabled-for-all-sites is set to true; in Seamonkey, check similar settings under Edit > Preferences > Advanced > Hardware AccelerationAffected if WebGL is enabled AND the version is in the affected range (vulnerable only when WebGL is active)
User is affected if they have Firefox below 7.0 or Seamonkey below 2.4 with WebGL enabled in their browser settings

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.
dbcve · scoped2.47.0
Upgrade Mozilla Firefox to version 7.0 or later, or SeaMonkey to version 2.4 or later, to obtain the patched WebGL implementation.
Firefox 7.0 or later; SeaMonkey 2.4 or later
- Upgrade Mozilla Firefox to version 7.0 or later
- Upgrade SeaMonkey to version 2.4 or later
- Restart the browser after upgrade
- Verify the version by checking About Firefox or About SeaMonkey
