CVE-2013-5592
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 · uneditedMultiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 25.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code 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.

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.
-
Verify Mozilla Firefox is installedCheck for Firefox executable or application. On Windows: look in Program Files or Program Files (x86) for Mozilla Firefox folder. On macOS: check /Applications for Firefox.app. On Linux: run 'which firefox' or check /usr/lib/firefoxAffected if Firefox is not present on the system
-
Determine installed Firefox versionOpen Firefox, click menu > Help > About Firefox, or type 'about:support' in address bar, or run 'firefox --version' from command lineAffected if Version displayed is 24.0 or lower, or matches 19.0, 19.0.1, 19.0.2, 20.0, 20.0.1, 21.0, 22.0, 23.0, or 23.0.1
-
Confirm version against affected listCompare your installed version number to the affected ranges: versions <= 24.0 and specifically 19.0, 19.0.1, 19.0.2, 20.0, 20.0.1, 21.0, 22.0, 23.0, 23.0.1Affected if Installed version appears in the affected list
A user is affected if their installed Firefox version is 24.0 or lower, or matches any of the specific affected versions 19.0.x, 20.0.x, 21.0, 22.0, or 23.0.x.

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 · scopedUpgrade Mozilla Firefox to version 25.0 or later to remediate these vulnerabilities.
Firefox 25.0 or later (current stable release recommended)
- 1. Back up any important browser data (bookmarks, passwords, extensions)
- 2. Close all Firefox instances
- 3. Download Firefox 25.0 or later from the official Mozilla website (www.mozilla.org)
- 4. Run the installer and follow the prompts to upgrade
- 5. After installation, verify the version by navigating to Help > About Firefox
- 6. Ensure the version shows 25.0 or higher
- 7. Re-enable any disabled add-ons that are compatible with the new version
- 8. Test critical web applications to ensure functionality
