Secunia reports :
A vulnerability in sircd can be exploited by a malicious person to
compromise a vulnerable system. The vulnerability is caused by a
boundary error in the code handling reverse DNS lookups, when a user
connects to the service. If the FQDN (Fully Qualified Domain Name)
returned is excessively long, the allocated buffer is overflowed
making it possible to execute arbitrary code on the system with the
privileges of the sircd daemon.
