From 2.0.0 until 4.1.2, decoding an attacker-supplied 32-bit floating-point TIFF as Image<HalfVector4> and applying HistogramEqualization can produce a non-finite or out-of-range luminance in ColorNumerics.GetBT709Luminance. GrayscaleLevelsRowOperation.Invoke uses the resulting value as an unchecked histogram offset, causing an unsafe out-of-range access and process termination. Adaptive Histogram Equalization and AutoLevel are not affected by this report. This issue is fixed in version 4.1.2.","state":0,"publishedAt":"2026-10-06T17:47:17.503+00:00","modifiedAt":"2026-10-07T17:07:48.107+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-j3p4-wp97-rph4","https://github.com/SixLabors/ImageSharp/pull/3187","https://github.com/SixLabors/ImageSharp/commit/c4c4bf292298c026df470db1a17ff826515fd95d","https://github.com/SixLabors/ImageSharp/releases/tag/v4.1.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106113","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106113","identifiers":["CVE-2026-106113"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
