Race condition in the Mozilla Maintenance Service in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 on Windows allows local users to write to arbitrary files and consequently gain privileges via vectors involving a hard link to a log file during an update.

Security readout for executives and security teams

This is an old Firefox local privilege escalation issue on Windows. A local user could abuse a race condition in the Mozilla Maintenance Service during updates to write to arbitrary files and potentially gain higher privileges. The main business concern is legacy Windows endpoints running affected Firefox versions. Likely exposure is limited to legacy Windows systems running Firefox before 40.0 or Firefox ESR 38.x before 38.2 with the Mozilla Maintenance Service present. The bundle does not establish exposure for current supported Firefox releases. Treat as high priority only where legacy affected Firefox exists on Windows. For fully updated environments, this is mainly a hygiene and asset-discovery issue rather than an urgent incident signal. Mitigation focus: Upgrade Firefox to 40.0 or later, or Firefox ESR to 38.2 or later.; Prefer moving affected endpoints to a currently supported Firefox release.; Check Mozilla and OS vendor advisories for any environment-specific guidance..
