The SVG Filters implementation in Mozilla Firefox before 3.6.28 and 4.x through 10.0, Firefox ESR 10.x before 10.0.3, Thunderbird before 3.1.20 and 5.0 through 10.0, Thunderbird ESR 10.x before 10.0.3, and SeaMonkey before 2.8 might allow remote attackers to obtain sensitive information from process memory via vectors that trigger an out-of-bounds read.

Security readout for executives and security teams

This is an old Mozilla browser and mail-client memory disclosure flaw. A malicious web page or content handled by affected Mozilla components could cause an out-of-bounds read and expose sensitive process memory. The listed affected versions are from 2012, so current risk is mainly unmanaged legacy systems. Exposure is most likely on legacy desktops, kiosks, lab systems, or embedded workflows still running the affected Mozilla versions or OS packages from that period. Treat as legacy hygiene unless affected software is still present. If found, prioritize removal or upgrade because browser and mail-client memory disclosure can expose sensitive session or document data. Mitigation focus: Upgrade Firefox, Thunderbird, SeaMonkey, or distribution packages beyond the fixed versions named by vendors.; Remove or isolate unsupported Mozilla-era clients from production and internet-facing browsing workflows.; Check Mozilla and Linux distribution advisories for exact package names and supported update paths..
