PACKAGE : ethereal
SUMMARY : Several remote vulnerabilities

RELEASES : 8, 9

DESCRIPTION
Ethereal[1] is a powerful network traffic analyzer with a graphical
user interface (GUI).
This update fixes several vulnerabilities[2] in Ethereal:
CAN-2004-0176: Stefan Esser discovered thirteen buffer overflows in
the dissector of the NetFlow, IGAP, EIGRP, PGM, IrDA, BGP, ISUP, and
TCAP protocol dissectors[3].
CAN-2004-0365: Jonathan Heussser discovered a denial of service
vulnerability in the RADIUS protocol dissector[4].
CAN-2004-0367: A zero-length presentation protocol selector can be
exploited to cause a denial of service[5].
These vulnerabilities can be exploited by a attacker who is able to
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 (characterizing a denial of service
condition) or, in the case of the buffer overflow vulnerabilities,
may execute arbitrary code with the privileges of the user running it
(usually root).
SOLUTION
It is recommended that all Ethereal users upgrade their packages.
