Use-after-free vulnerability in the nsHTMLCSSUtils::CreateCSSPropertyTxn function in Mozilla Firefox before 16.0, Firefox ESR 10.x before 10.0.8, Thunderbird before 16.0, Thunderbird ESR 10.x before 10.0.8, and SeaMonkey before 2.13 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.

Security readout for executives and security teams

This is an old Mozilla memory-safety flaw that could let a remote attacker crash affected applications or potentially run code. It applies to legacy Firefox, Thunderbird, and SeaMonkey releases, not current supported versions based on the supplied record. Exposure is most likely where obsolete Mozilla clients remain: Firefox before 16.0, Firefox ESR 10.x before 10.0.8, Thunderbird before 16.0, Thunderbird ESR 10.x before 10.0.8, or SeaMonkey before 2.13. Prioritize remediation if any legacy Mozilla clients remain in production or sensitive user environments. The business risk is mainly from outdated endpoint software that can process remote content and potentially lead to code execution. Mitigation focus: Upgrade Firefox, Thunderbird, and SeaMonkey beyond the fixed versions named in the CVE record.; Apply Linux distribution updates referenced by Debian, Ubuntu, Red Hat, SUSE, or Mandriva advisories.; Remove unsupported Mozilla ESR 10-era clients from managed environments..
