{"id":"CVE-2026-106118","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-106118","generatedAt":"2026-10-28T10:47:51.708Z","title":"The mismatch causes attacker-controlled out-of-bounds writes, heap corruption, and process termination even with legal per-row run codes.","description":"ImageSharp is a 2D graphics library. 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.","published":"2026-10-06T19:17:43.000Z","lastModified":"2026-10-06T20:17:18.000Z","status":"Awaiting Analysis","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-787"],"affected":[],"epss":{"score":0.00595,"percentile":0.48246,"date":"2026-10-27","history":[{"date":"2026-10-07","score":0.00603,"percentile":0.47188}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.60%).
