Integer overflow in Gimp
CVE-2026-2271
A flaw was found in GIMP's PSP (Paint Shop Pro) file parser. A remote attacker could exploit an integer overflow vulnerability in the read_creator_block() function by providing a specially crafted PSP image file. This vulnerability occurs when a 32-bit length value from the file is used for memory allocation without proper validation, leading to a heap overflow and an out-of-bounds write. Successful exploitation could result in an application level denial of service.
