How to fix?

Upgrade Debian:11 lrzip to version 0.631+git180517-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream lrzip package and not the lrzip package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

The lzo1x_decompress function in lzo1x_d.ch in LZO 2.08, as used in lrzip 0.631, allows remote attackers to cause a denial of service (invalid memory read and application crash) via a crafted archive.
