Technical details
A heap-based buffer overflow exists in GIMP's PSP file loader due to a mismatch between the allocated buffer size and the amount of data decompressed when processing compressed selection channels. The vulnerability is triggered via network-reachable attack vector (user must open a malicious PSP file), requiring user interaction. An attacker can craft a malicious PSP file that, when opened in GIMP, causes memory corruption leading to a crash (denial of service) or arbitrary code execution. The issue is classified as CWE-787 (Out-of-bounds Write). No mitigation or patch information is currently available according to Red Hat.
