漏洞描述
中文描述:
Cisco IOS和IOS XE Software都是美国思科（Cisco）公司为其网络设备开发的操作系统。DHCP relay是其中的一个用于实现在不同子网和物理网段之间处理和转发dhcp信息的功能的组件。 Cisco IOS 12.2版本至15.6版本和Cisco IOS XE Software中的DHCP relay子系统存在缓冲区溢出漏洞。远程攻击者可通过向受影响系统发送特制的DHCP Version 4(DHCPv4)数据包利用该漏洞造成拒绝服务（重新加载）。
英文描述:
The DHCP relay subsystem of Cisco IOS 12.2 through 15.6 and Cisco IOS XE Software contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code and gain full control of an affected system. The attacker could also cause an affected system to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to a buffer overflow condition in the DHCP relay subsystem of the affected software. An attacker could exploit this vulnerability by sending a crafted DHCP Version 4 (DHCPv4) packet to an affected system. A successful exploit could allow the attacker to execute arbitrary code and gain full control of the affected system or cause the affected system to reload, resulting in a DoS condition. Cisco Bug IDs: CSCsm45390, CSCuw77959.
