Description
Stack-based buffer overflow in the IceWarpServer.APIObject ActiveX control in api.dll in IceWarp Merak Mail Server 9.4.1 might allow context-dependent attackers to execute arbitrary code via a large value in the second argument to the Base64FileEncode method, as possibly demonstrated by a web application that accepts untrusted input for this method.
