CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE : xchat
SUMMARY :
DATE : 2002-01-18 11:05:00
ID : CLA-2002:453
RELEVANT
RELEASES : 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0

DESCRIPTION
XChat is a graphical IRC client available in most linux
distributions.
zen-parse discovered[1] a vulnerability in the xchat CTCP PING
handler which could be exploited by an attacker to trick the xchat
IRC user into sending arbitrary IRC commands to the server (a typical
example is a command to give channel operator status to the
attacker).
SOLUTION
All xchat users should upgrade.
Notice that CL 7.0 (xchat 1.7.7) users are not vulnerable by default
since the configuration variable "percascii" which controls the
vulnerable feature is set to 0.
