Mandriva Linux Security Advisory MDKSA-2007:051
http://www.mandriva.com/security/
_______________________________________________________________________

Package : snort
Date : February 28, 2007
Affected: 2006.0, 2007.0, Corporate 4.0, Multi Network Firewall 2.0
_______________________________________________________________________

Problem Description:

Algorithmic complexity vulnerability in Snort before 2.6.1, during
predicate evaluation in rule matching for certain rules, allows remote
attackers to cause a denial of service (CPU consumption and detection
outage) via crafted network traffic, aka a backtracking attack.

Updated packages have been patched to address this issue.
