CVE-2026-62438

Plug-in crash via PAA dimension integer overflow

Published Oct 16, 2026 · Updated Oct 16, 2026

GIMP's PAA loader allows attackers to crash the image plug-in through an out-of-bounds read triggered by a crafted texture file. Dimension arithmetic overflows during decompression, causing an undersized allocation that subsequent processing reads beyond. A user must open or preview the file; the supplied record also identifies potential disclosure of process memory, without establishing a reliable disclosure path.
