Important context from https://lists.debian.org/debian-security- announce/2024/msg00057.html :
Andres Freund discovered that the upstream source tarballs for xz-utils, the XZ-format compression utilities, are compromised and inject malicious code, at build time, into the resulting liblzma5 library. Right now no Debian stable versions are known to be affected. Compromised packages were part of the Debian testing, unstable and experimental distributions, with versions ranging from 5.5.1alpha-0.1 (uploaded on 2024-02-01), up to and including 5.6.1-1. The package has been reverted to use the upstream 5.4.5 code, which we have versioned 5.6.1+really5.4.5-1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2059417 Title: Sync xz-utils 5.6.1-1 (main) from Debian unstable (main) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xz-utils/+bug/2059417/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
