How to fix?

Upgrade Debian:9 bzip2 to version 1.0.5-0.1 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.

bzlib.c in bzip2 before 1.0.5 allows user-assisted remote attackers to cause a denial of service (crash) via a crafted file that triggers a buffer over-read, as demonstrated by the PROTOS GENOME test suite for Archive Formats.
