Use-after-free vulnerability in Mozilla Firefox 4.x through 10.0, Firefox ESR 10.x before 10.0.3, Thunderbird 5.0 through 10.0, Thunderbird ESR 10.x before 10.0.3, and SeaMonkey before 2.8 on 32-bit Windows 7 platforms allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors involving use of the file-open dialog in a child window, related to the IUnknown_QueryService function in the Windows shlwapi.dll library.

Security readout for executives and security teams

This is an old Mozilla memory-safety vulnerability affecting specific legacy Firefox, Thunderbird, and SeaMonkey versions on 32-bit Windows 7. A malicious remote trigger could crash the application and may allow code execution. Current business risk is mainly from unmanaged legacy endpoints still running these versions. Exposure is likely limited to legacy 32-bit Windows 7 systems running obsolete Mozilla browser or mail-client versions. Modern supported Mozilla releases are not listed as affected in the supplied sources. Treat this as a legacy exposure cleanup item unless affected systems are still in production. If they are, prioritize removal because the issue involves remote crash and possible code execution in obsolete client software. Mitigation focus: Upgrade Firefox ESR to 10.0.3 or later, where applicable.; Upgrade SeaMonkey to 2.8 or later.; Replace unsupported Firefox, Thunderbird, SeaMonkey, and Windows 7 deployments..
