DESCRIPTION
 The ircd package contains an Internet Relay Chat (IRC) server[1].
 
 Piotr Kucharski reported[2] a buffer overflow vulnerability that may
 allow an attacker to crash the ircd server, thus causing a denial of
 service condition. The package released with this advisory includes a
 patch[3] that fixes the problem.
 
 The Common Vulnerabilities and Exposures project (cve.mitre.org) has
 assigned the name CAN-2003-0864[4] to this issue.


SOLUTION
 All users of the ircd package should upgrade.
 
 IMPORTANT: After the update, it is necessary to restart the ircd
 server manually in order to load the new, non-vulnerable version. In
 order to do that, please run the following command as root:
 
 # /sbin/service ircd restart
