CVE-2024-3094: LZMA/XZ security report

Thought the group might find this interesting.

From Red Hat:

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.

Perhaps admin might sticky this one instead of having more of these threads pop up, at least until this category 5 hurricane of an exploit is fully fleshed out and realized. No disrespect siva but this is about the 5th thread on this subject.

My references weren't related directly to Devuan but I get your point.

fun enough, systemd does link xz-utils so machines running systemd with xz-utils 5.6.0 are extra compromised with an init level backdoor...
