Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - XZ Utils provide a general-purpose data-compression library plus command-line tools. In XZ Utils
 5.3.3alpha to 5.8.0, the multithreaded .xz decoder in liblzma has a bug where invalid input can at least
 result in a crash. The effects include heap use after free and writing to an address based on the null

 stable branches, but a standalone patch is available that applies to all affected releases.
