Fedora Update Notification

Product     : Fedora Core 2
Name        : unarj
Version     : 2.63a                      
Release     : 7                  
Summary     : An uncompressor for .arj format archive files.
Description :
The UNARJ program is used to uncompress .arj format archives.  The .arj
format archive was mostly used on DOS machines.

Install the unarj package if you need to uncompress .arj format

Update Information:

A buffer overflow bug has been discovered in unarj when handling long
file names contained in an archive. An attacker could create an archive
with a specially crafted path which could cause unarj to crash or
execute arbitrary instructions.  The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0947 to
this issue.

Additionally, a path traversal vulnerability exists in unarj which
allows an attacker to extract files to the parent ("..") directory. When
used recursively, this vulnerability can be used to overwrite critical
system files and programs.

Users of unarj are advised to upgrade to these packages.
