CVE-2026-106065
Gimp: gimp: heap buffer overflow in pcx export on oversized image dimensions
A heap-based buffer overflow was found in GIMP’s PCX export plug-in. For images with extremely large width and height, buffer allocation uses overflowing 32-bit width * height arithmetic while subsequent GEGL operations use the full extent, after integer overflow in size calculation
Fixes and workarounds
Workaround
Restrict PCX export to trusted images and reasonable dimension limits
