Subject: [Snort-sigs] new rule for detect LPD on hpux
Date: Thu, 27 Oct 2005 11:14:08 +0200 (CEST) 
Hi,

please check and add this new rule :

exploit.rules:alert tcp $EXTERNAL_NET any -> $HOME_NET 515 (msg:"EXPLOIT HPUX LPD overflow attempt"; flow:to_server,established;
content:"|24 7B 49 46 53 7D|"; reference:cve,2005-3277; reference:bugtraq,15136;
classtype:attempted-dos; )

This rule detect exploit on lpd over hpux with "${IFS}" content (msf exploit), but this rule not detect shell metacharacters ("`" or single backquote).

Improve are welcome.

Regards
Rmkml
