# CVE-2026-106065: Gimp: gimp: heap buffer overflow in pcx export on oversized image dimensions

Status: published. Published: 2026-10-07. Updated: 2026-11-05.

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

- workaround: Restrict PCX export to trusted images and reasonable dimension limits (source: CNA: redhat)
