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.

Additionally there were problems with two rules in the snort-rules package for 2008.0 that is also fixed with this update.

Update :

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers
