漏洞描述
中文描述:
Cisco ASA是美国思科（Cisco）公司的一套防火墙设备。该设备还包括IPS（入侵防御系统）、SSL VPN、IPSec VPN、反垃圾邮件等功能。 Cisco Adaptive Security Appliances (ASA) 5500系列设备中的DHCP服务器、Cisco Catalyst 6500系列设备软件7.2(5.8)之前的7.0版本、7.2(5.8)之前的7.1版本、7.2(5.8)之前的7.2版本、8.0(5.28)之前的8.0版本、8.1(2.56)之前的8.1版本、8.2(5.27)之前的8.2版本、8.3(2.31)之前的8.3版本、8.4(3.10)之前的8.4版本、8.5(1.9)之前的8.5版本、8.6(1.5)之前的8.6版本中的ASA Services Module (ASASM)中存在漏洞，该漏洞源于没有正确为DHCP报文分配内存。远程攻击者利用该漏洞通过一系列特制的IPv4报文，导致拒绝服务（设备重载）。
英文描述:
The DHCP server on Cisco Adaptive Security Appliances (ASA) 5500 series devices, and the ASA Services Module (ASASM) in Cisco Catalyst 6500 series devices, with software 7.0 before 7.2(5.8), 7.1 before 7.2(5.8), 7.2 before 7.2(5.8), 8.0 before 8.0(5.28), 8.1 before 8.1(2.56), 8.2 before 8.2(5.27), 8.3 before 8.3(2.31), 8.4 before 8.4(3.10), 8.5 before 8.5(1.9), and 8.6 before 8.6(1.5) does not properly allocate memory for DHCP packets, which allows remote attackers to cause a denial of service (device reload) via a series of crafted IPv4 packets, aka Bug ID CSCtw84068.
