CVE-2007-1497  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 2.6.21 or higher.

Overview

nf_conntrack in netfilter in the Linux kernel before 2.6.20.3 does not set nfctinfo during reassembly of fragmented packets, which leaves the default value as IP_CT_ESTABLISHED and might allow remote attackers to bypass certain rulesets using IPv6 fragments.
