Gimp: gimp: heap buffer overflow due to integer overflow in fits image loader_CVE-2026-40915

{
    "lastseen": "",
    "description": "A flaw was found in GIMP. A remote attacker could exploit an integer overflow vulnerability in the FITS image loader by providing a specially crafted FITS file. This integer overflow leads to a zero-byte memory allocation, which is then subjected to a heap buffer overflow when processing pixel data. Successful exploitation could result in a denial of service (DoS) or potentially arbitrary code execution.",
