CVE-2024-3094 PoC — Xz: malicious code in distributed source

Source
https://github.com/jfrog/cve-2024-3094-tools
Associated Vulnerability
Title:Xz: malicious code in distributed source (CVE-2024-3094)
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.
