Linux Kernel Netfilter nf_conntrack IPv6报文重组绕过规则漏洞
Vulnerability Description
Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。 Linux Kernel中netfilter的模块实现上存在漏洞，远程攻击者可能利用此漏洞绕过访问过滤。 netfilter的nf_conntrack函数在重组碎片IPv6报文期间没有设置nfctinfo，将默认值初始化为0，而这是IP_CT_ESTABLISHED的值，因此所有IPv6碎片都追踪为ESTABLISHED，这样攻击者就可以绕过某些
