CVE-ID: CVE-2024-3094
BDU-ID: 2024-02406
CVE-Crit: CRITICAL.
CVE-DESC.: Malicious code was discovered in xz source archives starting with version 5.6.0. Through a series of complex obfuscations, the liblzma build process extracts a pre-created object file from a disguised test file that exists in the source code, which is then used to modify certain functions in the liblzma code. The result is a modified liblzma library that can be used by any software associated with that library that intercepts and modifies data interactions with that library.
