IMPORTANT: The Gecko 1.8.0.x branch (Thunderbird 1.5.0.x series) has been deprecated. It is highly advisable to switch to the 2.0.0.x series to ensure that future security vulnerabilities will be fixed.

Impact key for security issues listed on the Mozilla Foundation Security Advisories webpage:

  • Critical: Vulnerability can be used to run attacker code and install software, requiring no user interaction beyond normal browsing.
  • High: Vulnerability can be used to gather sensitive data from sites in other windows or inject data or code into those sites, requiring no more than normal browsing actions.
  • Moderate: Vulnerabilities that would otherwise be High or Critical except they only work in uncommon non-default configurations or require the user to perform complicated and/or unlikely steps.
  • Low: Minor security vulnerabilities such as Denial of Service attacks, minor data leaks, or spoofs. (Undetectable spoofs of SSL indicia would have "High" impact because those are generally used to steal sensitive data intended for other sites.)
