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." } ], "affected": [ { "vendor": "GNOME", "product": "GIMP", "packageName": "gimp", "collectionURL": "https://gitlab.gnome.org/GNOME/gimp", "defaultStatus": "affected" }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "gimp:2.8", "defaultStatus": "affected", "versions": [ { "version": "8100020260824165450.4c9c024f", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "cpes": [ "cpe:/a:redhat:enterprise_linux:8::appstream" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "gimp", "defaultStatus": "affected", "versions": [ { "version": "2:3.0.4-4.el9_8.9", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "cpes": [ "cpe:/a:redhat:enterprise_linux:9::appstream" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "gimp", "defaultStatus": "affected", "versions": [ { "version": "2:2.99.8-4.el9_4.19", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "cpes": [ "cpe:/a:redhat:rhel_e4s:9.4::appstream" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9.6 Extended Update Support", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "gimp", "defaultStatus": "affected", "versions": [ { "version": "2:2.99.8-4.el9_6.20", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "cpes": [ "cpe:/a:redhat:rhel_eus:9.6::appstream" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 6", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "gimp", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:6" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 7", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "gimp", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:7" ] } ], "references": [ { "url": "https://access.redhat.com/errata/RHSA-2026:50817", "name": "RHSA-2026:50817", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ] }, { "url": "https://access.redhat.com/errata/RHSA-2026:62507", "name": "RHSA-2026:62507", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ] }, { "url": "https://access.redhat.com/errata/RHSA-2026:73768", "name": "RHSA-2026:73768", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ] }, { "url": "https://access.redhat.com/errata/RHSA-2026:80509", "name": "RHSA-2026:80509", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ] }, { "url": "https://access.redhat.com/security/cve/CVE-2026-66758", "tags": [ "vdb-entry", "x_refsource_REDHAT" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2507475", "name": "RHBZ#2507475", "tags": [ "issue-tracking", "x_refsource_REDHAT" ] }, { "url": "https://gitlab.gnome.org/GNOME/gimp/-/issues/16528" } ], "datePublic": "2026-07-07T00:00:00.000Z", "problemTypes": [ { "descriptions": [ { "cweId": "CWE-190", "description": "Integer Overflow or Wraparound", "lang": "en", "type": "CWE" } ] } ], "x_redhatCweChain": "CWE-190: Integer Overflow or Wraparound", "workarounds": [ { "lang": "en", "value": "To mitigate this vulnerability, do not open FITS files from untrusted sources with GIMP." } ], "timeline": [ { "lang": "en", "time": "2026-07-07T00:00:00.000Z", "value": "Reported to Red Hat." }, { "lang": "en", "time": "2026-07-07T00:00:00.000Z", "value": "Made public." } ], "credits": [ { "lang": "en", "value": "Red Hat would like to thank Tristan Madani for reporting this issue." } ], "providerMetadata": { "orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2026-10-12T02:08:13.155Z" }, "x_generator": { "engine": "cvelib 1.8.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-07-28T03:56:52.707001Z", "id": "CVE-2026-66758", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-07-29T18:16:51.197Z" } } ] } }
