Gimp: gimp: heap buffer overflow in hot color filter on oversized image

Published Oct 7, 2026 CVSS 3.1 · 6.3 Medium EPSS < 1% KEV · Not listed
Description
A heap-based buffer overflow was found in GIMP’s Hot color filter plug-in. For very large images, a pixel buffer is allocated using overflowing 32-bit width * height (and related) arithmetic while the filter’s pixel access path uses the true image size, after integer overflow in the allocation size

Remediation

Vendor Workaround
