From 2.0.0 until 4.1.2, ExifReader.ReadValues64 trusts the 64-bit BigTIFF IFD entry count and iterates once per declared entry. When fewer than 20 bytes remain, ExifReader.ReadValue64 returns without advancing the stream or terminating the outer loop, so a small malformed BigTIFF can keep one decoder thread executing for an attacker-controlled duration. This report does not claim worker-pool exhaustion. This issue is fixed in version 4.1.2."}], "lastModified": "2026-10-24T01:24:27.543", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:sixlabors:imagesharp:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FA378490-EF2F-4A3F-B62B-188E95240AC8", "versionEndExcluding": "3.2.0", "versionStartIncluding": "2.0.0"}, {"criteria": "cpe:2.3:a:sixlabors:imagesharp:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F920B012-BBFB-40DB-B201-165EBA6645D7", "versionEndExcluding": "4.1.2", "versionStartIncluding": "4.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
