A local buffer overrun vulnerability has been reported for Silly Poker. The problem occurs due to insufficient bounds checking when handling user-supplied data. As a result, an attacker may be capable of controlling the execution flow of the sillypoker program and effectivley executing arbitrary code with elevated privileges.
