Integer overflow in the make_filter_table function in pixops/pixops.c in gdk-pixbuf before 2.31.5, as used in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 on Linux, Google Chrome on Linux, and other products, allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow and application crash) via crafted bitmap dimensions that are mishandled during scaling.

Security readout for executives and security teams

CVE-2015-4491 is an old image-processing flaw in gdk-pixbuf used by Linux desktop software and browsers. A specially crafted bitmap could trigger memory corruption during image scaling, potentially crashing the application or enabling code execution. Current business risk mainly depends on whether legacy Linux packages or embedded appliances still ship vulnerable gdk-pixbuf or affected browsers. Exposure is most likely in unpatched Linux systems, legacy desktop images, kiosk environments, or products bundling old gdk-pixbuf/browser libraries. Modern distributions should already have vendor updates, but long-lived appliances and frozen workstation builds need confirmation. Prioritize validation where Linux systems process untrusted images, browse the web, or run kiosk-style applications. For fully patched modern fleets this is likely a hygiene check; for legacy or embedded Linux estates, it deserves scheduled remediation and exception tracking. Mitigation focus: Upgrade gdk-pixbuf to 2.31.5 or a vendor-fixed package.; Apply relevant browser updates for Firefox, Firefox ESR, and Linux Chrome packages.; Patch Linux distributions using Debian, Ubuntu, Red Hat, Fedora, or SUSE advisories as applicable..
