  00692205 DE280513 Web agent crashes when the machines use IPV6 addresses

 

Resolution

 

The defect is caused when using Ipv6 address and accessing to Web Agent
Server.

There is possibility of a crash when client requests HOST header
contain IPv6 address.

Reproduce sequence is as below:

***********************************

If you set the hosts file on your browser PC as 

10.0.0.1 host.example.com

Then reaching the request : 

  http://host.example.com/test/index.html 

Then the error.log shows the lines : 

  terminate called after throwing an instance of 'std::out_of_range' 
  what(): basic_string::at 
  [Fri Feb 24 15:35:31 2017] [notice] child pid 11974 exit signal Aborted (6)   

***********************************

As above, there was a bug in the code that when we were trying to
append the port when there is an ipv6 address as the hostname.
