{"id":"CVE-2026-34533","summary":"iccDEV: UB in CIccCalculatorFunc::ApplySequence()","details":"iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger Undefined Behavior (UB) in CIccCalculatorFunc::ApplySequence() due to invalid enum values being loaded for icChannelFuncSignature. The issue is observable under UBSan as a “load of value … not a valid value for type icChannelFuncSignature”, indicating a type/enum value confusion scenario during ICC profile processing. This issue has been patched in version 2.3.1.6.","aliases":["GHSA-8jj3-77m7-c3pq"],"modified":"2026-04-10T05:43:02.610740Z","published":"2026-03-31T21:56:28.390Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34533.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-758"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34533.json"},{"type":"REPORT","url":"https://github.com/InternationalColorConsortium/iccDEV/issues/664"},{"type":"FIX","url":"https://github.com/InternationalColorConsortium/iccDEV/pull/681"},{"type":"ADVISORY","url":"https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-8jj3-77m7-c3pq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34533"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/internationalcolorconsortium/iccdev","events":[{"introduced":"0"},{"fixed":"e280b0ad4b5574594c6a987bfa3ceb4f196f4b34"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2.3.1.6"}]}}],"versions":["v2.2.6","v2.3.1","v2.3.1.1","v2.3.1.2","v2.3.1.3","v2.3.1.4","v2.3.1.5","wasm-v2.3.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-34533.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
