CVE-2012-4444
Published: 9 November 2012
The ip6_frag_queue function in net/ipv6/reassembly.c in the Linux kernel before 2.6.36 allows remote attackers to bypass intended network restrictions via overlapping IPv6 fragments.
From the Ubuntu Security Team
Zhang Zuotao discovered a bug in the Linux kernel's handling of overlapping fragments in ipv6. A remote attacker could exploit this flaw to bypass firewalls and initial new network connections that should have been blocked by the firewall.
