sudosh -- buffer overflow

Description:

ISS reports:

sudosh2 and sudosh3 are vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the replay() function. By persuading a victim to replay a specially-crafted recorded sudo session, a local attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
