 The pointer desc in UpdateSDTinDB could be allocated by the function it is
 retrieve from (GetServiceDescriptor()). Then it could be leaked if certain
 failure paths are followed. Also because it is not always checked for
 null, it could segfault when dereferenced and is null.

 The patch used an std::auto_ptr to manage desc instead and adds any
 necessary checks for null.
