Attackers can supply a crafted MNG file with MHDR, DHDR and a multi-record ORDR chunk to applications calling mng_read or mng_readdisplay, writing attacker-controlled data past the allocation and crashing the application.","categories":["Unclassified"],"product":"libmng","vendor":"libmng","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112008","source_modified_at":"2026-10-19T19:04:44.302Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"libmng","vendor":"libmng","versions":[{"version":"0","lessThanOrEqual":"2.0.3","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00143,"percentile":0.03301,"score_date":"2026-10-23"},"published_at":"2026-10-18T11:38:31.288Z","modified_at":"2026-10-19T19:04:44.302Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-112008","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T19:04:44.302Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-112008","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://hackmd.io/@haindpwn/libmng-ordr-chunk-store-oob-write","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://sourceforge.net/projects/libmng/files/libmng-devel/2.0.3/","tags":["product"]},{"source":"CVE List","url":"https://sourceforge.net/projects/libmng/","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/libmng-through-2.0.3-heap-buffer-overflow-via-ordr-chunk-reader-mng-read-ordr","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-19T19:04:30.730248Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-19T19:04:44.302Z","content_hash":"ae8aff7935959e94937416f1353a6e22f38dbc5cf153ef727bcc91f14044e16b"}}
