Mandrake Linux Security Update Advisory
__________________________________________________ ______________________

Package name: kdenetwork
Advisory ID: MDKSA-2002:080
Date: November 21st, 2002

Affected versions: 9.0
__________________________________________________ ______________________

Problem Description:

The SuSE security team discovered two vulnerabilities in the KDE
lanbrowsing service during an audit. The LISa network daemon and
"reslisa", a restricted version of LISa are used to identify servers
on the local network by using the URL type "lan://" and "rlan://"
respectively. A buffer overflow was discovered in the lisa daemon
that can be exploited by an attacker on the local network to obtain
root privilege on a machine running the lisa daemon. Another
buffer overflow was found in the lan:// URL handler, which can be
exploited by a remote attacker to gain access to the victim user's
account.

Only Mandrake Linux 9.0 comes with the LISa network daemon; all
previous versions do not contain the network daemon and are as such
not vulnerable.
