CVE-2024-3094 Information

Description

Malicious code was discovered in the upstream tarballs of xz starting with version 5.6.0. 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.
