RHEL 2.1 / 3 / 4 : ncompress (RHSA-2006:0663)

This script is Copyright (C) 2006-2016 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated ncompress packages that address a security issue and fix bugs
are now available.

This update has been rated as having low security impact by the Red
Hat Security Response Team.

The ncompress package contains file compression and decompression
utilities, which are compatible with the original UNIX compress
utility (.Z file extensions).

Tavis Ormandy of the Google Security Team discovered a lack of bounds
checking in ncompress. An attacker could create a carefully crafted
file that could execute arbitrary code if uncompressed by a victim.

In addition, two bugs that affected Red Hat Enterprise Linux 4
ncompress packages were fixed :

* The display statistics and compression results in verbose mode were
not shown when operating on zero length files.

* An attempt to compress zero length files resulted in an unexpected
return code.

Users of ncompress are advised to upgrade to these updated packages,
which contain backported patches to correct these issues.
