RHSA-2004-536: ncompress

Vulnerability Assessment Summary
Check for the version of the ncompress packages

Detailed Explanation for this Vulnerability Assessment

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 a possible hacker 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.
