SGI Security Advisory has warned the /usr/etc/talkd daemon, installed by default on IRIX 6.5 systems, contains a format string vulnerability. This could allow an attacker to exploit the system, either through DNS or a remote client.
These issues have been corrected in the 6.5.10 and later releases of IRIX.
