中文描述:

Cisco Adaptive Security Appliance（ASA） CX Context-Aware Security是美国思科（Cisco）公司的一款用于扩展ASA平台的附加服务模块。 Cisco ASA CX Context-Aware Security模块中的data plane IP fragment handler存在安全漏洞，该漏洞源于程序没有正确的处理IP段。远程攻击者可利用该漏洞造成拒绝服务。

英文描述:

A vulnerability in the data plane IP fragment handler of the Cisco Adaptive Security Appliance (ASA) CX Context-Aware Security module could allow an unauthenticated, remote attacker to cause the CX module to be unable to process further traffic, resulting in a denial of service (DoS) condition. The vulnerability is due to improper handling of IP fragments. An attacker could exploit this vulnerability by sending crafted fragmented IP traffic across the CX module. An exploit could allow the attacker to exhaust free packet buffers in shared memory (SHM), causing the CX module to be unable to process further traffic, resulting in a DoS condition. This vulnerability affects all versions of the ASA CX Context-Aware Security module. Cisco has not released and will not release software updates that address this vulnerability. There are no workarounds that address this vulnerability. Cisco Bug IDs: CSCva62946.
