{"id":"CVE-2026-27799","summary":"ImageMagick has a heap Buffer Over-read in its DJVU image format handler","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in the DJVU image format handler. The vulnerability occurs due to integer truncation when calculating the stride (row size) for pixel buffer allocation. The stride calculation overflows a 32-bit signed integer, resulting in an out-of-bounds memory reads. Versions 7.1.2-15 and 6.9.13-40 contain a patch.","aliases":["GHSA-r99p-5442-q2x2"],"modified":"2026-05-16T11:52:55.568540510Z","published":"2026-02-25T23:20:25.204Z","related":["SUSE-SU-2026:0851-1","SUSE-SU-2026:0852-1","SUSE-SU-2026:0853-1","SUSE-SU-2026:0854-1","openSUSE-SU-2026:20337-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27799.json","cna_assigner":"GitHub_M","unresolved_ranges":[{"extracted_events":[{"fixed":"6.9.13-40"}],"source":"AFFECTED_FIELD"}],"cwe_ids":["CWE-122","CWE-126"]},"references":[{"type":"WEB","url":"https://github.com/dlemstra/Magick.NET/releases/tag/14.10.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27799.json"},{"type":"ADVISORY","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-r99p-5442-q2x2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27799"},{"type":"FIX","url":"https://github.com/ImageMagick/ImageMagick/commit/e87695b3227978ad70b967b8d054baaf8ac2cced"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L"}]}
