CVE-2013-0772: The RasterImage::DrawFrameTo function in Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMon...

Security readout for executives and security teams

CVE-2013-0772 is an old Mozilla image-handling flaw. A malicious GIF could make vulnerable Firefox, Thunderbird, or SeaMonkey read outside expected memory, potentially exposing process memory or crashing the application. Business risk is mainly from unmanaged legacy systems that still run the affected versions. Exposure is most likely on legacy desktops, VDI images, kiosks, or servers with old Mozilla packages from Ubuntu, openSUSE, or Red Hat channels. Current supported Mozilla clients should not be affected if fully patched. Treat this as a legacy hygiene issue unless affected clients still exist in production. If they do, prioritize patching because the attack surface is ordinary web or email content and the impact includes information disclosure and crashes. Mitigation focus: Upgrade Firefox to 19.0 or later where applicable.; Upgrade Thunderbird to 17.0.3 or later where applicable.; Upgrade SeaMonkey to 2.16 or later where applicable..
