CVE-2026-106064
Gimp: gimp: heap buffer overflow in gif export on oversized image dimensions
A heap-based buffer overflow was found in GIMP’s GIF export plug-in. Exporting an image with very large width and height can cause 32-bit overflow when computing the pixel buffer size. The plug-in allocates a buffer based on the wrapped value while GEGL writes using the true image extent, rooted in integer overflow
Fixes and workarounds
Workaround
Do not export untrusted high-resolution images to GIF; enforce maximum width/height in batch or scripted export pipelines
