CVE-2026-58380

Gimp: gimp: stack buffer overflow in pnmscanner_gettoken()

CVSS 3.1 7.3 HIGHCheck source for fixed versionsKEV status unknown
Original advisory

cve-program · CVE-2026-58380

Published

A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.
