NetBSD PPPoE发现脚本远程拒绝服务漏洞

BUGTRAQ ID:30838 CNCAN ID：CNCAN-2008082706 NetBSD是一款基于BSD的操作系统。 NetBSD包含的pppoe4代码处理恶意报文存在问题，远程攻击者可以利用漏洞触发内核访问越界内容而导致内核崩溃，造成拒绝服务攻击。 在客户端和访问集中器之间的会话连接之前，处理PPPoE连接的早期状态的关键代码存在问题。在"discovery"阶段的报文由多个可变长度"tags"装载同一个PPPoE报文中，每个标签将被检查，而且针对全部报文大小的长度进行了验证。不过在长度检查过程中存在一个缺陷，允许把下一个TAG的指针越界移动到报文后最多4字节的位置。...
