CONECTIVA LINUX SECURITY ANNOUNCEMENT
- --------------------------------------------------------------------------

PACKAGE : ethereal
SUMMARY : Fix for ethereal vulnerabilities
DATE : 2004-01-07 17:38:00
ID : CLA-2004:801
RELEVANT
RELEASES : 8, 9

- -------------------------------------------------------------------------

DESCRIPTION
Ethereal[1] is a powerful network traffic analyzer with a graphical
user interface (GUI).

This update announcement addresses vulnerabilities[2] in the SMB
(CAN-2003-1012[3]) and Q.931 (CAN-2003-1013[4]) protocol dissectors.

These vulnerabilities can be exploited by an attacker who can insert
crafted packets in the wire being monitored by ethereal or make an
user open a trace file with such packets inside. When reading this
data, Ethereal will crash. The possibility of execution of arbitrary
code has not been investigated.

SOLUTION
It is recommended that all Ethereal users upgrade their packages.
