17494 Falsing on non IE6 systems

["Weir, Jason" <jason.weir () nhrs org>]

Tons of false positives on machines running IE7 & 8...

Maybe do a content match on the IE6 user agent - something like
content:"compatible; MSIE 6."

alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"WEB-CLIENT
Microsoft Internet Explorer Long URL Buffer Overflow attempt";
flow:established,to_server; urilen:>260; content:"GET"; http_method;
content:"HTTP|2F|1|2E|1|0D 0A|"; metadata:service http;

classtype:attempted-user; sid:17494; rev:1;)
