Cisco PIX/ASA DHCP中继远程拒绝服务漏洞

PIX是一款防火墙设备，可为用户和应用提供策略强化、多载体攻击防护和安全连接服务；自适应安全设备（ASA）是可提供安全和VPN服务的模块化平台。 配置为使用DHCP中继代理功能的PIX和ASA设备中实现上存在漏洞，远程攻击者可能利用此漏洞导致设备拒绝服务。 如果从多个DHCP服务器接收到了DHCPACK消息响应DHCP客户端的DHCPREQUEST或DHCPINFORM消息的话，就可能导致消耗1550字节的块内存。仅在通过dhcprelay server命令配置了多个DHCP服务器的情况下才会出现这个漏洞。一旦完全消耗了1550字节块内存，设备就会开始丢包，导致无法转发报文。 Cisco...
