CVE-2015-7192
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 accessibility-tools feature in Mozilla Firefox before 42.0 on OS X improperly interacts with the implementation of the TABLE element, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code by using an NSAccessibilityIndexAttribute value to reference a row index.
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 confidenceA vulnerability in Firefox's OS X accessibility-tools feature allows attackers to trigger a denial of service or potentially achieve arbitrary code execution by manipulating NSAccessibilityIndexAttribute values when referencing TABLE element row indices. The flaw stems from improper input validation in the accessibility API's interaction with table row indexing.

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 OS X is the running operating systemRun 'uname -s' or check System Preferences to confirm the operating system is OS X. This vulnerability only affects Firefox on OS X platforms.Affected if The system is running any OS other than OS X (the vulnerability does not apply to Windows or Linux Firefox installations)
-
Confirm Firefox browser is installedCheck for Firefox installation by looking in /Applications/Firefox.app or running 'mdfind kMDItemCFBundleIdentifier == org.mozilla.firefox' in Terminal.Affected if Firefox is not installed on the system
-
Determine installed Firefox versionOpen Firefox, go to Help > About Firefox, or run '/Applications/Firefox.app/Contents/MacOS/firefox -version' in Terminal to retrieve the version number.Affected if The installed Firefox version is 41.0.2 or earlier (versions 42.0 and later are not affected)
-
Check if Firefox accessibility features are enabledIn Firefox, type 'about:config' in the address bar, then search for 'accessibility'. Verify if 'accessibility.force遥' or related accessibility settings are enabled, or check System Preferences > Accessibility to confirm OS-level accessibility access is granted to Firefox.Affected if Accessibility features are enabled in Firefox (the vulnerability exploits the OS X accessibility API interaction with table row indexing)
A user is affected if they are running Firefox version 41.0.2 or earlier on OS X with accessibility features enabled, as the flaw requires the accessibility API to be accessible for exploitation.

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 Firefox to version 42.0 or later on all affected OS X systems. If immediate patching is not possible, consider restricting access to untrusted content or using alternative accessibility configurations until the update can be deployed.
