Fedora Update Notification
FEDORA-2004-414
2004-11-11
---------------------------------------------------------------------

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 archives.



---------------------------------------------------------------------
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.
