When processing a FITS image file, the plugin calculates memory allocation sizes using signed 32-bit integers for width and height. If a crafted file sets both values to large values, their product exceeds 2^31 and overflows, resulting in an undersized heap-based buffer allocation. This integer overflow issue results in a heap-based buffer overflow when cfitsio subsequently writes a full row of pixels in the buffer, causing memory corruption, potentially leading to arbitrary code execution or a denial of service.","score":7.8,"severity":"high","published":"2026-07-27T19:07:12.789Z","modified":"2026-11-04T23:01:02.540Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"GNOME","name":"GIMP","platforms":[],"versions":[],"defaultStatus":"affected","cpes":[],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-66758"},{"vendor":"Red
