#5289 closed defect (fixed)

SIScan::UpdateSDTinDB can leak desc or segfault because of a given pointer

Description

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.
