# CVE-2024-3094

> 10.0 CRITICAL

## Beschreibung

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.
