IBM AIX 'rpc.ttdbserver' Remote Buffer Overflow Vulnerability

IBM AIX is prone to a remote buffer-overflow vulnerability because the software fails to perform adequate boundary checks on user-supplied data.

Remote attackers can exploit this issue to execute arbitrary code with superuser privileges, which can result in the complete compromise of affected computers. Failed exploit attempts will cause a denial-of-service condition.
