{"id":"CVE-2026-106114","summary":"ImageSharp: ICC CLUT parsing allocates from unvalidated channel and grid dimensions","details":"ImageSharp is a 2D graphics library. From 1.0.0-beta0001 until 4.1.2, ICC CLUT parsing calculates allocation sizes from attacker-declared channel and grid dimensions before confirming that the profile contains the declared values. IccDataReader.ReadClutF32 can request a large float array, and earlier public IccProfile.Entries parsing paths can allocate a large jagged representation, from a short truncated profile. In version 4, automatic image conversion reaches the parser when DecoderOptions.ColorProfileHandling is Convert; the default Preserve mode avoids that conversion path. The demonstrated impact is memory pressure and input-validation failure, not unhandled process termination. This issue is fixed in version 4.1.2.","aliases":["GHSA-gwg2-r3hj-4w44"],"modified":"2026-10-08T02:49:19.204343932Z","published":"2026-10-06T17:48:41.736Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-789"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/106xxx/CVE-2026-106114.json"},"references":[{"type":"WEB","url":"https://github.com/SixLabors/ImageSharp/releases/tag/v4.1.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/106xxx/CVE-2026-106114.json"},{"type":"ADVISORY","url":"https://github.com/SixLabors/ImageSharp/security/advisories/GHSA-gwg2-r3hj-4w44"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106114"},{"type":"FIX","url":"https://github.com/SixLabors/ImageSharp/commit/8de892a7623aa8a09ba2333b624c8d2eb98325df"},{"type":"FIX","url":"https://github.com/SixLabors/ImageSharp/pull/3187"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sixlabors/imagesharp","events":[{"introduced":"0"},{"fixed":"8de892a7623aa8a09ba2333b624c8d2eb98325df"},{"fixed":"dee414097e4be7bb35ef0209cf96bd0b61a7133a"}],"database_specific":{"extracted_events":[{"introduced":"1.0.0-beta0001"},{"fixed":"4.1.2"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v4.1.1","v4.1.0","v4.0.0","v3.1.0","v3.0.1","v3.0.0","v2.1.1","v2.1.0","v2.0.0","v1.0.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-106114.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
