Mandrake Linux Security Update Advisory
________________________________________________________________________
Package name: sharutils
Advisory ID: MDKSA-2002:052
Date: August 14th, 2002
Affected versions: 7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1,
Single Network Firewall 7.2
________________________________________________________________________
Problem Description:
The uudecode utility creates output files without checking to see if it
is about to write to a symlink or pipe. This could be exploited by a
local attacker to overwrite files or lead to privilege escalation if
users decode data into share directories, such as /tmp. This update
fixes this vulnerability by checking to see if the destination output
file is a symlink or pipe.

If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm". A list of
FTP mirrors can be obtained from:
http://www.mandrakesecure.net/en/ftp.php
Please verify the update prior to upgrading to ensure the integrity of
the downloaded package. You can do this with the command:
rpm --checksig <filename>
All packages are signed by MandrakeSoft for security. You can obtain
the GPG public key of the Mandrake Linux Security Team from:
https://www.mandrakesecure.net/RPM-GPG-KEYS
Please be aware that sometimes it takes the mirrors a few hours to
update.
