Debian DLA-1505-1 : zutils security update

high Nessus Plugin ID 117501

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

Solution

Upgrade the affected zutils, and zutils-dbg packages.
