xz-utils: Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0
CVE-2024-3094 is fixed in xz-utils on 1 platform, first by DEBIAN-CVE-2024-3094, released March 29, 2024. It is not reported as exploited. Patch Radar priority: Urgent.
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.
