From 3.0.0 until 4.1.1, decoding a strip TIFF using CCITT Group 3 or Modified Huffman compression can pass attacker-expanded runs to BitWriterUtils.WriteBits without first checking the current row width. T4TiffCompression.WritePixelRun can accumulate oversized makeup-code runs, and ModifiedHuffmanTiffCompression.Decompress validates the width only after writing. The unchecked writes can overflow the strip buffer, corrupt heap memory, and terminate the process. This strip-path vulnerability is distinct from the tiled decompressor-width mismatch. This issue is fixed in version 4.1.1."}], "lastModified": "2026-10-27T20:11:46.843", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:sixlabors:imagesharp:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A5FE5DFC-A93D-4ED7-A381-E2D581D983A8", "versionEndExcluding": "3.2.0", "versionStartIncluding": "3.0.0"}, {"criteria": "cpe:2.3:a:sixlabors:imagesharp:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "007EB800-626A-4644-9A71-FA026EFCC355", "versionEndExcluding": "4.1.1", "versionStartIncluding": "4.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
