Half-Life Format String Vulnerability
It has been reported that Half-Life clients may be prone to a format string vulnerability. The problem occurs when an invalid command is issued to the server, and an error response is returned and displayed by the client. If a format specifier were included within the invalid command, when displaying the error the format specifier would be interperted literally. This could potentially be exploited by a remote attacker to execute arbitrary code with the privileges of the Half-Life client.
Mitigation:
Ensure that all user-supplied input is properly validated and sanitized.
