From 3.0.0 until 4.1.1, tiled TIFF decoding allocates a destination buffer using TileWidth but TiffDecompressorsFactory.Create constructs T4, T6, and Modified Huffman decompressors using the full frame width. TiffDecoderCore.DecodeTilesChunky can therefore direct frame-width fax scanlines into a tile-width buffer when TileWidth is smaller than ImageWidth. The mismatch causes attacker-controlled out-of-bounds writes, heap corruption, and process termination even with legal per-row run codes. This tiled-path vulnerability is distinct from oversized CCITT runs in strip decoding. This issue is fixed in version 4.1.1.","state":0,"publishedAt":"2026-10-06T19:17:42.64+00:00","modifiedAt":"2026-10-06T20:17:17.703+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/SixLabors/ImageSharp/commit/9ee7d1dd5b62d8c9f16cc755e76828386bc2191f","https://github.com/SixLabors/ImageSharp/pull/3176","https://github.com/SixLabors/ImageSharp/releases/tag/v4.1.1","https://github.com/SixLabors/ImageSharp/security/advisories/GHSA-v76p-62qx-wwq2"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-106118","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-787"],"productCriteria":[],"sourceDates":{"published":"2026-10-06T19:17:42.640","lastModified":"2026-10-06T20:17:17.703"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
