PACKAGE   : ethereal
SUMMARY   : Fix for ethereal vulnerabilities
DATE      : 2003-11-07 16:08:00
ID        : CLA-2003:780
RELEVANT
RELEASES  : 7.0, 8, 9

DESCRIPTION
 Ethereal[1] is a powerful network traffic analyzer with a graphical
 user interface (GUI).
 
 This update announcement addresses several vulnerabilities[2] in
 ethereal versions prior to 0.9.16. 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. Successful exploitation of these vulnerabilities
 can lead to denial of service conditions and/or remote execution of
 arbitrary code.
 
 The following vulnerabilities have been fixed in the 0.9.16 version:
 
 - buffer overflow in the GTP protocol dissector (CAN-2003-0925)[3]
 - denial of service with ISAKMP or MEGACO packets (CAN-2003-0926)[4]
 - buffer overflow in the SOCKS protocol dissector (CAN-2003-0927)[5]


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