Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x before 3.1.1, and SeaMonkey before 2.0.6 permit cross-origin loading of CSS stylesheets even when the stylesheet download has an incorrect MIME type and the stylesheet document is malformed, which allows remote attackers to obtain sensitive information via a crafted document.

Security readout for executives and security teams

This old Mozilla vulnerability could let a malicious web page bypass browser same-origin protections and read sensitive cross-site information through malformed CSS handling. The listed affected products are legacy Firefox, Thunderbird, and SeaMonkey versions from 2010. There is no source-bundle evidence of active exploitation. Exposure is most plausible in unmanaged legacy desktops or embedded systems still running the affected Mozilla versions. Current supported Mozilla products are not identified as affected in the supplied sources. Treat as a legacy hygiene issue unless affected versions are still present. If found on active endpoints, prioritize removal or upgrade because browser-origin bypasses can expose sensitive data. Mitigation focus: Upgrade Firefox, Thunderbird, and SeaMonkey beyond the fixed versions named by Mozilla.; Remove unsupported legacy Mozilla applications from enterprise endpoints.; Check Mozilla advisory MFSA 2010-46 for vendor-specific upgrade guidance..
