漏洞描述
中文描述:
Cisco IOS Software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。 Cisco IOS Software和IOS XE Software中的DHCP option 82 encapsulation功能存在输入验证漏洞，该漏洞源于程序没有对option 82信息执行完整的输入校验。远程攻击者可通过发送特制的DHCPv4数据包利用该漏洞造成拒绝服务（设备重新加载）。
英文描述:
A vulnerability in the DHCP option 82 encapsulation functionality of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software performs incomplete input validation of option 82 information that it receives in DHCP Version 4 (DHCPv4) packets from DHCP relay agents. An attacker could exploit this vulnerability by sending a crafted DHCPv4 packet to an affected device. A successful exploit could allow the attacker to cause a heap overflow condition on the affected device, which will cause the device to reload and result in a DoS condition. Cisco Bug IDs: CSCvg62730.
