Technical description

ip6_tables in netfilter in the Linux kernel before 2.6.16.31 allows remote attackers to (1) bypass a rule that disallows a protocol, via a packet with the protocol header not located immediately after the fragment header, aka "ip6_tables protocol bypass bug;" and (2) bypass a rule that looks for a certain extension header, via a packet with an extension header outside the first fragment, aka "ip6_tables extension header bypass bug."

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
