GENTOO LINUX SECURITY ANNOUNCEMENT 200211-004
- - --------------------------------------------------------------------
PACKAGE : kdenetwork
SUMMARY : rlogin.protocol and telnet.protocol URL KIO Vulnerability
resLISa / LISa Vulnerabilities
DATE : DATUM
EXPLOIT : local & remote
- - --------------------------------------------------------------------
from KDE advisory 20021111-1 :
The implementation of the rlogin protocol in all of the affected
systems, and the implementation of the telnet protocol in affected
KDE 2 systems, allows a carefully crafted URL in an HTML page,
HTML email or other KIO-enabled application to execute arbitrary
commands on the system using the victim's account on the
vulnerable machine.
The vulnerability potentially enables local or remote attackers
to compromise a victim's account and execute arbitrary commands
on the local system with the victim's privileges, such as erasing
files, accessing data or installing trojans.

from KDE advisory 20021111-2 :
The resLISa daemon contains a buffer overflow vulnerability which
potentially enables any local user to obtain access to a raw socket
if 'reslisa' is installed SUID root. This vulnerability was
discovered by the iDEFENSE security team and Texonet.
The lisa daemon contains a buffer overflow vulnerability which
potentially enables any local user, as well any any remote attacker
on the LAN who is able to gain control of the LISa port (7741 by
default), to obtain root privileges.
In addition, a remote attacker potentially may be able to gain
access to a victim's account by using an "lan://" URL in an HTML
page or via another KDE application. These vulnerabilities were
discovered by Olaf Kirch at SuSE Linux AG.
