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.","epss":{"date":"2026-11-01","percentile":0.22275,"score":0.00296},"exploits":[{"kind":"exploit","source":"secalert@redhat.com","url":"https://gitlab.gnome.org/GNOME/gimp/-/issues/16528"}],"kev":null,"metrics":[{"score":7.8,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},{"score":7.8,"severity":"high","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793614632587,"publishedAt":1785179232789,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:50817"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:62507"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:73768"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:80509"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:93589"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-66758"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2507475"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.gnome.org/GNOME/gimp/-/issues/16528"},{"source":"secalert@redhat.com","tags":["Issue Tracking"],"url":"https://access.redhat.com/errata/RHSA-2026:50817"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:62507"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:73768"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:80509"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:93589"},{"source":"secalert@redhat.com","tags":["Vendor Advisory"],"url":"https://access.redhat.com/security/cve/CVE-2026-66758"},{"source":"secalert@redhat.com","tags":["Issue Tracking","Vendor Advisory"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2507475"},{"source":"secalert@redhat.com","tags":["Exploit","Issue Tracking","Vendor Advisory"],"url":"https://gitlab.gnome.org/GNOME/gimp/-/issues/16528"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"To mitigate this vulnerability, do not open FITS files from untrusted sources with GIMP."}],"revision":"c09e197af304b0214989d089f672f54c63e10c73cff5ce37708ed438312e9298","sources":[{"modifiedAt":1793613536142,"name":"CNA: redhat","retrievedAt":1793614117727,"url":"https://www.cve.org/CVERecord?id=CVE-2026-66758"},{"modifiedAt":1793614632587,"name":"NVD","retrievedAt":1793621750469,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-66758"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793614125678,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-66758"}],"ssvc":{"assessedAt":1785211012707,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"Gimp: integer overflow in file-fits plugin causes a heap-based buffer overflow on crafted fits images","updatedAt":1793621750469}
