PACKAGE : ethereal
SUMMARY : Fix for ethereal vulnerabilities

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.
