Is there a snort signature out for this as of yet?
Yes, in the latest signature set includes, at the end of smtp.rules: alert tcp $EXTERNAL_NET any -> $SMTP_SERVERS 25 (msg:"SMTP From comment overflow attempt"; flow:to_server,established; content:"From\:"; content:"<><><><><><><><><><><><><><><><><><><><><><>"; distance:0; content:"("; distance:1; content:")"; distance:1; reference:cve,CAN-2002-1337; reference:url,www.kb.cert.org/vuls/id/398025; classtype:attempted-admin; sid:2087; rev:2;) It false-positives pretty easily, but does seem to catch the currently-discussed attacks. -Bennett
