{"id":"CVE-2026-27799","state":"PUBLISHED","title":"ImageMagick has a heap Buffer Over-read in its DJVU image format handler","description":"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.","publishedAt":"2026-02-25T23:20:25.204Z","updatedAt":"2026-02-26T17:04:08.122Z","severity":{"score":4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["ImageMagick ImageMagick"],"affected":[{"vendor":"ImageMagick","product":"ImageMagick","versions":[{"version":"< 6.9.13-40","status":"affected"},{"version":">= 7.0.0, < 7.1.2-15","status":"affected"}]}],"references":["https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-r99p-5442-q2x2","https://github.com/ImageMagick/ImageMagick/commit/e87695b3227978ad70b967b8d054baaf8ac2cced","https://github.com/dlemstra/Magick.NET/releases/tag/14.10.3"],"weaknesses":["CWE-122","CWE-126"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/27xxx/CVE-2026-27799.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-27799","state":"PUBLISHED","datePublished":"2026-02-25T23:20:25.204Z","dateUpdated":"2026-02-26T17:04:08.122Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-24T02:31:33.266Z"},"containers":{"cna":{"title":"ImageMagick has a heap Buffer Over-read in its DJVU image format handler","descriptions":[{"lang":"en","value":"ImageMagick is free and open-source software used for editing and manipulating digital images.
