QID 48253: Possible Exposure to xzlib Detected on MacOS

xz is a general purpose data compression format present in nearly every Linux distribution, both community projects and commercial product distributions.

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. Affected Version
xz v5.6.0 and v5.6.1
