IPv6 implementations insecurely update Forwarding Information Base

Overview A vulnerability in some implementations of the IPv6 Neighbor Discovery Protocol may allow a nearby attacker to intercept traffic or cause congested links to become overloaded. Description IPv6 networks use the Neighbor Discovery Protocol NDP to detect and locate routers and other on-link...

CVE-2008-2464

The mldinput function in sys/netinet6/mld6.c in the kernel in NetBSD 4.0, FreeBSD, and KAME, when INET6 is enabled, allows remote attackers to cause a denial of service divide-by-zero error and panic via a malformed ICMPv6 Multicast Listener Discovery MLD query with a certain Maximum Response Del...

CVE-2008-2464

The CVE-2008-2464 issue affects NetBSD 4.0, FreeBSD, and KAME kernels with INET6 enabled, where the mld_input function in sys/netinet6/mld6.c mishandles certain ICMPv6 MLD-QUERY Maximum-Response-Delay values. This can allow remote attackers on the local link to trigger a divide-by-zero error and ...

NetBSD ICMPv6 MLD报文远程拒绝服务漏洞

BUGTRAQ ID: 31026 CVE ID: CVE-2008-2464 CNCVE ID：CNCVE-20082464 NetBSD是一款开放源代码的操作系统。 NetBSD不正确处理ICMPv6 MLD查询报文，远程攻击者可以利用漏洞对系统进行拒绝服务攻击。 NetBSD不正确处理Maximum-Response-Delay字段设置小于0x0010的ICMPv6 MLD-QUERY报文，接收到这种类型报文时，NetBSD代码会由于除零错误而导致系统停止响应，造成拒绝服务攻击。 NetBSD Current NetBSD 4.0 厂商解决方案 只有使用如下选项编译的内核受此漏洞影...

FreeBSD畸形ICMPv6报文远程拒绝服务漏洞

BUGTRAQ ID: 31004 CVE ID：CVE-2008-3530 CNCVE ID：CNCVE-20083530 FreeBSD是一款开放源代码的操作系统。 FreeBSD处理ICMPv6 'Packet Too Big Message'报文存在问题，远程攻击者可以利用漏洞使内核的TCP堆栈出现panic，造成拒绝服务攻击。 针对入站的ICMPv6 'Packet Too Big Message'报文，在针对为到目的路径拟议新MTU时缺少充分检查。当内核配置为能处理IPv6报文，并激活IPv6 TCP套接字时，特殊构建的ICMPv6 'Packet Too Big...
