[原文]The nfattr_to_tcp function in ip_conntrack_proto_tcp.c in ctnetlink in Linux kernel 2.6.14 up to allows attackers to cause a denial of service (kernel oops) via an update message without private protocol information, which triggers a null dereference.

[CNNVD]Linux kernel ip_conntrack_proto_tcp.c拒绝服务漏洞(CNNVD-200511-389)

        Linux Kernel是开放源码操作系统Linux所使用的内核。
        Linux kernel 2.6.14至2.6.14.3的ctnetlink中的ip_conntrack_proto_tcp.c内的nfattr_to_tcp函数,可让攻击者通过没有私有协议信息的更新消息(这会触发空的取消引用)使系统拒绝服务(内核崩溃)。
