漏洞描述
中文描述:

Cisco Small Business 300 Series是美国思科（Cisco）公司的一款企业级管理型交换机。 Cisco Small Business 300 Series中DHCP和TFTP功能之间的交互存在资源管理错误漏洞。该漏洞源于网络系统或产品对系统资源（如内存、磁盘空间、文件等）的管理不当。

英文描述:

A vulnerability in the interactions between the DHCP and TFTP features for Cisco Small Business 300 Series (Sx300) Managed Switches could allow an unauthenticated, remote attacker to cause the device to become low on system memory, which in turn could lead to an unexpected reload of the device and result in a denial of service (DoS) condition on an affected device. The vulnerability is due to a failure to free system memory when an unexpected DHCP request is received. An attacker could exploit this vulnerability by sending a crafted DHCP packet to the targeted device. A successful exploit could allow the attacker to cause an unexpected reload of the device.
