A flaw was found in GIMP. Heap-buffer-overflow vulnerability exists in the fread_pascal_string function when processing a specially crafted PSD (Photoshop Document) file. This occurs because the buffer allocated for a Pascal string is not properly null-terminated, leading to an out-of-bounds read when strlen() is subsequently called. Successfully exploiting this vulnerability can cause the application to crash, resulting in an application level Denial of Service.

    GIMP: PSD loader: heap-buffer-overflow in fread_pascal_string() (no null terminator) (CVE-2026-2239)

    An integer overflow vulnerability has been identified in the PSP (Paint Shop Pro) file parser of GIMP. The     issue occurs in the read_creator_block() function, where the Creator metadata block is processed.
    Specifically, a 32-bit length value read from the file is used directly for memory allocation without     proper validation. (CVE-2026-2271)
