XZ is the successor to the Lempel-Ziv/Markov-chain Algorithm compression format, which provides memory-hungry but powerful compression (often better than bzip2) and fast, easy decompression.

This package provides the command line tools for working with XZ compression, including xz, unxz, xzcat, xzgrep, and so on. They can also handle the older LZMA format, and if invoked via appropriate symlinks will emulate the behavior of the commands in the lzma package.

The XZ format is similar to the older LZMA format but includes some improvements for general use:

* 'file' magic for detecting XZ files; * crc64 data integrity check; * limited random-access reading support; * improved support for multithreading (not used in xz-utils); * support for flushing the encoder.

On the Linux Mint Software Manager the Xz-utils says Version 5.2.5-2ubuntu1. But the Backdoor exploit was affecting Xz-utils versions 5.6.0 and 5.6.1. So check your version. For me - before confirming versions I uninstalled the version that was installed on my machine quickly just to be safe. But it must've been version 5.2.5-2ubuntu1 on my machine which supposedly is safe.

Flagging this, this was the package which had a potential backdoor in it... not sure how one can detect these on this or other packages though.
