CVE-2026-58380

A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscannergettoken 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,...

CVE-2026-58380

GIMP contains a vulnerability in its PNM file format parser where the function pnmscanner_gettoken() writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one loop boundary check. This memory corruption could lead to denial of service or arbitrary code execut...
