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."}], "lastModified": "2026-10-12T03:17:20.213", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:gimp:gimp:3.0.8:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0866C0EF-59AE-4AB9-8D0F-7C75CD20F77E"}, {"criteria": "cpe:2.3:a:gimp:gimp:3.2.4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6F076B19-3582-4EC8-9625-D2E716652890"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:6.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "2F6AB192-9D7D-4A9A-8995-E53A9DE9EAFC"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:7.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "142AD0DD-4CF3-4D74-9442-459CE3347E3A"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F4CFF558-3C47-480D-A2F0-BABF26042943"}, {"criteria": "cpe:2.3:o:redhat:enterprise_linux:9.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7F6FB57C-2BC7-487C-96DD-132683AEB35D"}], "operator": "OR"}]}], "sourceIdentifier": "secalert@redhat.com"}
