Title: Xz: malicious code in distributed source
Cve id: CVE-2024-3094
Cve state: PUBLISHED
Cve assigner short name: redhat
Cve date updated: 03/29/2024
Cve description: Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0. The tarballs included extra .m4 files, which contained instructions for building with automake that did not exist in the repository. These instructions, through a series of complex obfuscations, extract a prebuilt object file from one of the test archives, which is then used to modify specific functions in the code while building the liblzma package. This issue results in liblzma being used by additional software, like sshd, to provide functionality that will be interpreted by the modified functions.
