Technical details
A buffer overflow vulnerability exists in the 'scheme' component of the login utility on SGI IRIX systems. The flaw is triggered by providing specially crafted, overly long input to the login/scheme command, which fails to perform adequate bounds checking. Because this utility typically runs with elevated privileges, a local attacker can exploit the overflow to overwrite memory and redirect execution flow to arbitrary code. Successful exploitation results in a complete privilege escalation from a standard user to the root account.
