Just to make sure there is no confusion, this is regarding the 
vulnerability found in the Back Orifice preprocessor in Snort 
2.4.0-2.4.2. Snort 2.4.3 has been released to correct the issue and 
provide detection capabilities for attempts to exploit the 
vulnerability. This was announced on the site and mailing lists on 
October 18, 2005 at 9:18am EDT.

Complete details are available at 

As always, let me know if anyone has any questions.
