OpenBSD DHCPD服务程序远程栈溢出漏洞
Vulnerability Description
OpenBSD是一款开放源代码Unix类操作系统。 OpenBSD系统的DHCP协议实现上存在缓冲区溢出漏洞，远程攻击者可能利用此漏洞控制服务器。 OpenBSD的options.c文件中的cons_options()函数没有正确地处理DHCP请求。如果远程攻击者所发送的DHCP请求中指定最大消息大小小于最小IP MTU(278)的话，就会在OpenBSD中导致dhcpd(8)覆盖栈缓冲区，执行任意指令。 漏洞存在于负责处理从客户端所接收到的DHCP选项的函数中。在src/usr.sbin/dhcpd/o
