{"id":"DEBIAN-CVE-2026-112008","details":"libmng through 2.0.3 contains a heap-based buffer overflow vulnerability in mng_read_ordr() that allows attackers to corrupt heap memory because ORDR entry buffers are sized by 5-byte on-wire records instead of 8-byte in-memory entries. 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.","modified":"2026-10-23T18:05:33.349611767Z","published":"2026-10-18T12:17:13.247Z","upstream":["CVE-2026-112008"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-112008"}],"affected":[{"package":{"name":"libmng","ecosystem":"Debian:12","purl":"pkg:deb/debian/libmng?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.10+dfsg-3.1","2.0.3+dfsg-1","2.0.3+dfsg-2","2.0.3+dfsg-3","2.0.3+dfsg-4","2.0.3+dfsg-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-112008.json"}},{"package":{"name":"libmng","ecosystem":"Debian:13","purl":"pkg:deb/debian/libmng?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.10+dfsg-3.1","2.0.3+dfsg-1","2.0.3+dfsg-2","2.0.3+dfsg-3","2.0.3+dfsg-4","2.0.3+dfsg-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-112008.json"}},{"package":{"name":"libmng","ecosystem":"Debian:14","purl":"pkg:deb/debian/libmng?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.10+dfsg-3.1","2.0.3+dfsg-1","2.0.3+dfsg-2","2.0.3+dfsg-3","2.0.3+dfsg-4","2.0.3+dfsg-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-112008.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
