{"id":"CVE-2026-34556","summary":"iccDEV: HBO in icAnsiToUtf8()","details":"iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, there is a heap-buffer-overflow (HBO) in icAnsiToUtf8() in the XML conversion path. The issue is triggered by a crafted ICC profile which causes icAnsiToUtf8(std::string&, char const*) to treat an input buffer as a C-string and call operations that rely on strlen()/null-termination. AddressSanitizer reports an out-of-bounds READ of size 115 past a 114-byte heap allocation, with the failure observed while running the iccToXml tool. This issue has been patched in version 2.3.1.6.","aliases":["GHSA-p9wm-xfv4-43qg"],"modified":"2026-04-10T05:43:04.122542Z","published":"2026-03-31T22:22:47.259Z","database_specific":{"cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34556.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34556.json"},{"type":"REPORT","url":"https://github.com/InternationalColorConsortium/iccDEV/issues/734"},{"type":"FIX","url":"https://github.com/InternationalColorConsortium/iccDEV/pull/740"},{"type":"ADVISORY","url":"https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-p9wm-xfv4-43qg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34556"}],"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-2026-34556.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"}]}
