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.","state":0,"publishedAt":"2026-10-18T11:38:31.288+00:00","modifiedAt":"2026-10-19T19:04:44.302+00:00","affected":[{"ecosystem":"https://sourceforge.net/projects/libmng/","name":"libmng","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"libmng\",\n                    \"product\": \"libmng\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"2.0.3\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"collectionURL\": \"https://sourceforge.net/projects/libmng/\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","score":6.1,"severity":"MEDIUM"}],"references":["https://hackmd.io/@haindpwn/libmng-ordr-chunk-store-oob-write","https://sourceforge.net/projects/libmng/files/libmng-devel/2.0.3/","https://sourceforge.net/projects/libmng/","https://www.vulncheck.com/advisories/libmng-through-2.0.3-heap-buffer-overflow-via-ordr-chunk-reader-mng-read-ordr"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112008","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112008","identifiers":["CVE-2026-112008"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
