GIMP Image Parser Integer Overflow

A security vulnerability in A flaw (CVSS 4.3). Remediation should follow standard vulnerability management procedures.

GIMP's PSP file parser fails to validate 32-bit length values in the read_creator_block() function, allowing local attackers to trigger integer overflow and heap buffer overflow via specially crafted PSP image files, resulting in application-level denial of service. Red Hat Enterprise Linux versions 6-9, Ubuntu (7 releases), Debian (9 releases), and SUSE are affected. No public exploit code or active exploitation has been identified at the time of analysis, though the vulnerability has been assigned ENISA EUVD ID EUVD-2026-16340 and tracked across major Linux distributions.
