"zutils version prior to version 1.8-pre2 contains a buffer overflow
vulnerability in zcat which happened with some input files when the
'-v, --show-nonprinting' option was used (or indirectly enabled). This
can result in potential denial of service or arbitrary code execution.
This attack appear is exploitable via the victim openning a crafted
compressed file and has been fixed in 1.8-pre2.

For Debian 8 'Jessie', this problem has been fixed in version
1.3-4+deb8u1.

We recommend that you upgrade your zutils packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
