CVE-2013-1706: Stack-based buffer overflow in maintenanceservice.exe in the Mozilla Maintenance Service in Mozilla Firefox...

Security readout for executives and security teams

This is an old Mozilla local privilege escalation flaw. On systems with vulnerable Firefox or Thunderbird versions and Mozilla Maintenance Service installed, a local user could use an overly long command-line pathname to gain higher privileges. The bundle does not show remote exploitation or active exploitation evidence. Exposure is most likely on unmanaged or legacy Windows endpoints retaining old Firefox or Thunderbird installations with Mozilla Maintenance Service. Current, normally updated Mozilla installations should not match the vulnerable version ranges described in the bundle. Treat this as a legacy hygiene and endpoint hardening issue. It is important where old Mozilla software remains installed, especially on shared systems, but the provided evidence does not support emergency response for active exploitation. Mitigation focus: Upgrade Firefox to 23.0 or later where applicable.; Upgrade Firefox ESR 17.x to 17.0.8 or later.; Upgrade Thunderbird and Thunderbird ESR 17.x to 17.0.8 or later..
