Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, does not properly handle injection of an ISINDEX element into an about:blank page, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges via vectors related to redirection to a chrome: URI.

Security readout for executives and security teams

This is an old Mozilla browser flaw where a malicious page could make vulnerable Firefox or SeaMonkey run JavaScript with browser-level privileges. That is more serious than ordinary webpage script execution because it crosses browser security boundaries. The exposure is mainly legacy systems still running the listed 2010-era versions. Exposure is most likely on unmanaged legacy desktops, old Linux distributions, kiosks, appliances, or lab systems still using the affected Mozilla versions. Current supported browser installations are not identified as affected in the supplied sources. Treat as high priority only where legacy Mozilla browsers remain in use. For modern managed fleets, the immediate business risk is likely low, but asset validation is still necessary because the impact crosses browser privilege boundaries. Mitigation focus: Upgrade Firefox to 3.5.16, 3.6.13, or later supported releases.; Upgrade SeaMonkey to 2.0.11 or later supported releases.; Retire unsupported legacy browsers where upgrade is not practical..
