Off-by-one error in the GeoIP module in the AMX Mod X 1.76d plugin for Half-Life Server might allow attackers to execute arbitrary code or cause a denial of service via unspecified input related to geolocation, which triggers an error message from the (1) geoip_code2 or (2) geoip_code3 function, leading to a buffer overflow.

Format string vulnerability in Sierra Half-Life build 1573 and earlier allows a remote attacker to execute arbitrary code via the map command.
