security of the package X11.Dt.ToolTalk.

There is a buffer overflow vulnerability in the ToolTalk library
libtt.a. A remote attacker can exploit this vulnerability when the
rpc.ttdbserver is enabled in /etc/inetd.conf. 

The successful exploitation of this vulnerability allows a remote
attacker to execute arbitrary code as the root user.

The following libraries and executables are vulnerable :

/usr/dt/lib/libtt.a /usr/dt/bin/rpc.ttdbserver."
