RHSA-2006-0663: ncompress

Vulnerability Assessment Summary
Check for the version of the ncompress packages

Detailed Explanation for this Vulnerability Assessment

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. A possible hacker could create a carefully crafted file
that could execute arbitrary code if uncompressed by a victim.
(CVE-2006-1168)

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.
