DESCRIPTION
 Ethereal is a powerful network traffic analyzer with an intuitive
 interface.
 
 This update addresses several vulnerabilities in ethereal <= 0.9.4 as
 stated[1][2] in the project's home page. The following protocol
 dissectors were vulnerable to various kinds of attacks (mainly DoS
 and arbitrary code execution): BGP, X11, DNS, GIOP, WCP, SOCKS, RSVP,
 AFS and LMP.
 
 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.


SOLUTION
 All ethereal users should upgrade their packages.
