CVE-2011-3092
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 · uneditedThe regex implementation in Google V8, as used in Google Chrome before 19.0.1084.46, allows remote attackers to cause a denial of service (invalid write operation) or possibly have unspecified other impact via unknown 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 · moderate confidenceVulnerability in the regex implementation of Google V8 JavaScript engine (used in Chrome pre-19.0.1084.46) allows remote attackers to cause an invalid memory write, leading to denial of service and potentially other unspecified impact via unknown attack vectors.

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 in the Chrome browser, or run 'google-chrome --version' from command lineAffected if The displayed version is 19.0.1084.45 or earlier (any version up to and including 19.0.1084.45)
-
Confirm V8 JavaScript engine is in useThe vulnerability is in V8 regex implementation; verify Chrome is using its built-in V8 engine (default state for Chrome)Affected if Chrome is using the default V8 JavaScript engine (this is the default configuration)
-
Verify regex functionality is accessibleThe vulnerability is triggered via unknown vectors involving regex processing; no specific configuration disable exists for this componentAffected if The V8 engine regex module is loaded and functional (standard Chrome operation)
If Google Chrome version is 19.0.1084.45 or earlier and using the default V8 engine, the environment is affected by this regex implementation vulnerability.
Generated from the published advisory. Verify against your own configuration.
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 · scopedUpdate Google Chrome to version 19.0.1084.46 or later. For standalone V8 usage, update to the patched V8 engine version containing the regex fix.
Chrome 19.0.1084.46 or later
- Ensure you are running Google Chrome version 19.0.1084.45 or earlier
- Navigate to Chrome menu > Help > About Google Chrome
- Chrome will check for updates automatically
- If an update is available, apply it to reach version 19.0.1084.46 or later
- Restart the browser to complete the update
