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.
