{"id":"UBUNTU-CVE-2024-40896","details":"In libxml2 2.11 before 2.11.9, 2.12 before 2.12.9, and 2.13 before 2.13.3, the SAX parser can produce events for external entities even if custom SAX handlers try to override entity content (by setting \"checked\"). This makes classic XXE attacks possible.","modified":"2026-02-04T03:10:10.354256Z","published":"2024-12-23T17:15:00Z","withdrawn":"2025-07-16T05:16:20Z","related":["CVE-2024-40896","USN-7215-1"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-40896"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-40896"},{"type":"REPORT","url":"https://ubuntu.com/security/notices/USN-7215-1"}],"affected":[{"package":{"name":"libxml2","ecosystem":"Ubuntu:24.10","purl":"pkg:deb/ubuntu/libxml2@2.12.7+dfsg-3ubuntu0.1?arch=source&distro=oracular"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.7+dfsg-3ubuntu0.1"}]}],"versions":["2.9.14+dfsg-1.3ubuntu3","2.12.7+dfsg-3"],"ecosystem_specific":{"ubuntu_priority":"medium","availability":"No subscription required","binaries":[{"binary_name":"libxml2","binary_version":"2.12.7+dfsg-3ubuntu0.1"},{"binary_name":"libxml2-dbgsym","binary_version":"2.12.7+dfsg-3ubuntu0.1"},{"binary_name":"libxml2-dev","binary_version":"2.12.7+dfsg-3ubuntu0.1"},{"binary_name":"libxml2-doc","binary_version":"2.12.7+dfsg-3ubuntu0.1"},{"binary_name":"libxml2-utils","binary_version":"2.12.7+dfsg-3ubuntu0.1"},{"binary_version":"2.12.7+dfsg-3ubuntu0.1","binary_name":"libxml2-utils-dbgsym"},{"binary_name":"python3-libxml2","binary_version":"2.12.7+dfsg-3ubuntu0.1"},{"binary_name":"python3-libxml2-dbgsym","binary_version":"2.12.7+dfsg-3ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-40896.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H"}]}
