How to fix?

Upgrade Debian:9 bzip2 to version 1.0.2-7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream bzip2 package and not the bzip2 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

bzip2 allows remote attackers to cause a denial of service (hard drive consumption) via a crafted bzip2 file that causes an infinite loop (a.k.a "decompression bomb").
