From 2.0.0 until 4.1.2, the TIFF CCITT Group 3 encoder allocates an undersized compressed-data buffer for narrow 1-bit images. TiffCcittCompressor.Initialize does not reserve enough space for the row data and T4 end-of-line codes, and T4BitCompressor.CompressStrip reaches unchecked writes when TiffCompression.CcittGroup3Fax is selected directly or inherited from decoded TIFF metadata. An attacker-controlled encode or decode-and-re-encode flow can write beyond the logical output span, corrupt process memory, and terminate the process. This issue is fixed in version 4.1.2.","state":0,"publishedAt":"2026-10-06T17:42:02.099+00:00","modifiedAt":"2026-10-09T01:19:50.868+00:00","affected":[{"ecosystem":"Vendor product","name":"ImageSharp","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"SixLabors\",\n                    \"product\": \"ImageSharp\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.0.0, < 4.1.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/security/advisories/GHSA-j9gm-c75j-xc9q","https://github.com/SixLabors/ImageSharp/pull/3187","https://github.com/SixLabors/ImageSharp/commit/a9498c6db3642ef92c712ebc81e706914ac16a95","https://github.com/SixLabors/ImageSharp/releases/tag/v4.1.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106110","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106110","identifiers":["CVE-2026-106110"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
