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 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

Remediation

Vendor Workaround

Restrict PCX export to trusted images and reasonable dimension limits
