alert udp $EXTERNAL_NET any -> $HOME_NET 69 (msg:"TFTP root directory"; 
content:"|0001|/"; offset:0; depth:3; reference:arachnids,138; 
reference:cve,CVE-1999-0183; classtype:bad-unknown; sid:520; rev:2;)

Yep that would in fact be impossible.. Sounds like mangling of alerts in 
snort, something which has been a problem with some snort versions in the 
past..
