["Crowell, Gary" <Gary.Crowell () experian com>]

Hi All,

I am running Snort 2.0.0 and the following commented out rule from
web-iis.rules causes snort to die.

        .
        .
####alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS $HTTP_PORTS (msg:"WEB-IIS
unicode directory traversal attempt"; flow:to_server,established;
content:"/..%c0%af../"; nocase; classtype:web-application-attack;
reference:cve,CVE-2000-0884; sid:981; rev:6;)
