RHEL 2.1 : ncompress (RHSA-2004:536)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated ncompress package that fixes a buffer overflow and problem
in the handling of files larger than 2 GB is now available.

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

A bug in the way ncompress handles long filenames has been discovered.
ncompress versions 4.2.4 and earlier contain a stack based buffer
overflow when handling very long filenames. It is possible that an
attacker could execute arbitrary code on a victims machine by tricking
the user into decompressing a carefully crafted filename. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2001-1413 to this issue.

This updated ncompress package also fixes a problem in the handling of
files larger than 2 GB.

All users of ncompress should upgrade to this updated package, which
contains fixes for these issues.
