Description OSIDB Bzimport 2026-03-26 11:34:44 UTC 
This issue is a heap buffer over-read in GIMP’s PCX file loader due to an off‑by‑one error in the bytesperline validation logic. A specially crafted PCX image can cause GIMP to read beyond the bounds of a heap buffer when opened, leading to out‑of‑bounds memory disclosure and possible crash. Exploitation requires user interaction (opening a malicious PCX file)
