Synopsis
The remote AIX host is missing a vendor-supplied security patch.
Description
The remote host is missing AIX PTF U829533, which is related to the 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.
Solution
Install the appropriate missing security-related fix.
