CVE-2026-58382

A flaw was found in GIMP's Jeff's Image Format (JIF) parser. A heap-based out-of-bounds write occurs in the ReadJeffsImage() function when a crafted JIF file supplies an invalid bits-per-pixel value that causes the unpack loop to write beyond the destination buffer. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.

A heap out-of-bounds write in the ReadJeffsImage() function can lead to memory corruption, potentially resulting in denial of service or arbitrary code execution. Successful exploitation requires a user to open a specially crafted JIF file with a build that includes the JIF import path.
