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.
