The pset utility, as shipped by SGI with Irix 5.x and 6.x through 6.3, contains a buffer overflow, which can allow any user on the system to execute arbitrary code on the machine as root. Pset is used to configure and administer processor groups in multiprocessor systems. By supplying a well crafted, long buffer as an argument, the return address on the stack is overwritten, allowing an attacker to execute code other than that which was intended.
