Description Adam Mariš 2016-10-06 12:59:01 UTC 
The IIS/ISAPI specific code implements special handling when a virtual host is present. The virtual host name and the URI are concatenated to create a virtual host mapping rule. It was found that the length checks prior to writing to the target buffer for this rule did not take account of the length of the virtual host name, creating the potential for a buffer overflow.
