{"id":"UBUNTU-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":"2026-10-28T20:15:43.868649227Z","published":"2026-10-18T12:17:00Z","upstream":["CVE-2026-112008"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-112008"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-112008"}],"affected":[{"package":{"name":"libmng","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libmng?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.2-0ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_name":"libmng2","binary_version":"2.0.2-0ubuntu3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-112008.json"}},{"package":{"name":"libmng","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libmng?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.2-0ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_name":"libmng2","binary_version":"2.0.2-0ubuntu3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-112008.json"}},{"package":{"name":"libmng","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libmng?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.3+dfsg-3"],"ecosystem_specific":{"binaries":[{"binary_name":"libmng2","binary_version":"2.0.3+dfsg-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-112008.json"}},{"package":{"name":"libmng","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libmng?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.3+dfsg-3"],"ecosystem_specific":{"binaries":[{"binary_name":"libmng2","binary_version":"2.0.3+dfsg-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-112008.json"}},{"package":{"name":"libmng","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libmng?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.3+dfsg-4","2.0.3+dfsg-4build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmng2","binary_version":"2.0.3+dfsg-4build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-112008.json"}},{"package":{"name":"libmng","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/libmng?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.3+dfsg-5"],"ecosystem_specific":{"binaries":[{"binary_name":"libmng2","binary_version":"2.0.3+dfsg-5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-112008.json"}},{"package":{"name":"libmng","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libmng?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.3+dfsg-4build1","2.0.3+dfsg-5"],"ecosystem_specific":{"binaries":[{"binary_version":"2.0.3+dfsg-5","binary_name":"libmng2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-112008.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H"},{"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"},{"type":"Ubuntu","score":"medium"}]}
