漏洞描述
中文描述:

Cisco IP Phone 7800和8800 Series中的Cisco Discovery Protocol或Link Layer Discovery Protocol (LLDP) 的实现存在资源管理错误漏洞，该漏洞源于程序缺少对Cisco Discovery Protocol or LLDP数据包报头字段进行程度验证。攻击者可通过发送恶意的数据包利用该漏洞造成电话重新加载，导致拒绝服务。以下产品和版本受到影响：Cisco IP Conference Phone 7832 12.5(1)SR1之前版本；IP Conference Phone 8832 12.5(1)SR1之前版本；IP Phone 7811 12.5(1)SR1之前版本；IP Phone 7821 12.5(1)SR1之前版本；IP Phone 7841 12.5(1)SR1之前版本；IP Phone 7861 12.5(1)SR1之前版本；IP Phone 8800 Series 12.5(1)SR1之前版本；IP Phone 8800 Series with Multiplatform Firmware 12.5(1)SR1之前版本；IP Phone 8800 Series - VPN feature 12.5(1)SR1之前版本；IP Phone 8861 12.5(1)SR1之前版本；IP Phone 8865 with Multiplatform Firmware 12.5(1)SR1之前版本；IP Phone 8865 12.5(1)SR1之前版本；Unified IP Conference Phone 8831 12.5(1)SR1之前版本；Unified IP Conference Phone 8831 for Third-Party Call Control 12.5(1)SR1之前版本；Wireless IP Phone 8821 12.5(1)SR1之前版本。

英文描述:

A vulnerability in the Cisco Discovery Protocol or Link Layer Discovery Protocol (LLDP) implementation for the Cisco IP Phone 7800 and 8800 Series could allow an unauthenticated, adjacent attacker to cause an affected phone to reload unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability is due to missing length validation of certain Cisco Discovery Protocol or LLDP packet header fields. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol or LLDP packet to the targeted phone. A successful exploit could allow the attacker to cause the affected phone to reload unexpectedly, resulting in a temporary DoS condition. Versions prior to 12.6(1)MN80 are affected.
