{"id":"DEBIAN-CVE-2024-3094","details":"Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0. \r Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which is then used to modify specific functions in the liblzma code. This results in a modified liblzma library that can be used by any software linked against this library, intercepting and modifying the data interaction with this library.","modified":"2026-09-15T09:02:56.950268684Z","published":"2024-03-29T17:15:21.150Z","upstream":["CVE-2024-3094"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-3094"}],"affected":[{"package":{"name":"xz-utils","ecosystem":"Debian:13","purl":"pkg:deb/debian/xz-utils?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.6.1+really5.4.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-3094.json"}},{"package":{"name":"xz-utils","ecosystem":"Debian:14","purl":"pkg:deb/debian/xz-utils?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.6.1+really5.4.5-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-3094.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
