SUMMARY : rlogin.protocol and telnet.protocol URL KIO Vulnerability |
| 10 |
resLISa / LISa Vulnerabilities |

| 16 |
from KDE advisory 20021111-1 : |
| 17 |
|
| 18 |
The implementation of the rlogin protocol in all of the affected |
| 19 |
systems, and the implementation of the telnet protocol in affected |
| 20 |
KDE 2 systems, allows a carefully crafted URL in an HTML page, |
| 21 |
HTML email or other KIO-enabled application to execute arbitrary |
| 22 |
commands on the system using the victim's account on the |
| 23 |
vulnerable machine. |
| 24 |
|
| 25 |
The vulnerability potentially enables local or remote attackers |
| 26 |
to compromise a victim's account and execute arbitrary commands |
| 27 |
on the local system with the victim's privileges, such as erasing |
| 28 |
files, accessing data or installing trojans. |

|
| 33 |
from KDE advisory 20021111-2 : |
| 34 |
|
| 35 |
The resLISa daemon contains a buffer overflow vulnerability which |
| 36 |
potentially enables any local user to obtain access to a raw socket |
| 37 |
if 'reslisa' is installed SUID root. This vulnerability was |
| 38 |
discovered by the iDEFENSE security team and Texonet. |
| 39 |
|
| 40 |
The lisa daemon contains a buffer overflow vulnerability which |
| 41 |
potentially enables any local user, as well any any remote attacker |
| 42 |
on the LAN who is able to gain control of the LISa port (7741 by |
| 43 |
default), to obtain root privileges. |
| 44 |
|
| 45 |
In addition, a remote attacker potentially may be able to gain |
| 46 |
access to a victim's account by using an "lan://" URL in an HTML |
| 47 |
page or via another KDE application. These vulnerabilities were |
| 48 |
discovered by Olaf Kirch at SuSE Linux AG. |
