Mandriva Linux Security Advisory 2009-259 - 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. The updated packages have been patched to prevent this. Additionally there were problems with two rules in the snort-rules package for 2008.0 that is also fixed with this update. Packages for 2008.0 are being provided due to extended support for Corporate products.
