漏洞描述
中文描述:

Cisco 3500、5500和8500 Series Wireless LAN Controller Software都是美国思科（Cisco）公司的无线局域网控制软件。 Cisco 3500、5500和8500 Series Wireless LAN Controller Software中的IP Version 4 (IPv4)片段重组功能存在资源管理错误漏洞，该漏洞源于在重组IPv4数据包时，出现了内部数据框架进程损坏的情况。远程攻击者可利用该漏洞造成拒绝服务（重新加载）。

英文描述:

A vulnerability in the IP Version 4 (IPv4) fragment reassembly function of Cisco 3500, 5500, and 8500 Series Wireless LAN Controller Software could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to a corruption of an internal data structure process that occurs when the affected software reassembles certain IPv4 packets. An attacker could exploit this vulnerability by sending certain malformed IPv4 fragments to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. This vulnerability affects all releases of 8.4 until the first fixed release for the 5500 and 8500 Series Wireless LAN Controllers and releases 8.5.103.0 and 8.5.105.0 for the 3500, 5500, and 8500 Series Wireless LAN Controllers. Cisco Bug IDs: CSCvf89222.
