Mandriva Linux Security Advisory MDVSA-2009:259
http://www.mandriva.com/security/
_______________________________________________________________________

Package : snort
Date : October 7, 2009
Affected: 2008.1
_______________________________________________________________________

Problem Description:

preprocessors/spp_frag3.c in Sourcefire Snort before 2.8.1 does not
properly identify packet fragments that have dissimilar TTL values,
which allows remote attackers to bypass detection rules by using a
different TTL for each fragment. (CVE-2008-1804)

The updated packages have been patched to prevent this.
