漏洞描述
中文描述:
Cisco Adaptive Security Appliance是美国思科（Cisco）公司的一个网络设备。用于保护各种规模的公司网络和数据中心。 Cisco Adaptive Security Appliance存在安全漏洞，该漏洞源于于建立 SSH 会话时出现逻辑错误。攻击者利用该漏洞导致系统拒绝服务。
英文描述:
A vulnerability in the SSH server of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition for the SSH server of an affected device. This vulnerability is due to a logic error when an SSH session is established. An attacker could exploit this vulnerability by sending crafted SSH messages to an affected device. A successful exploit could allow the attacker to exhaust available SSH resources on the affected device so that new SSH connections to the device are denied, resulting in a DoS condition. Existing SSH connections to the device would continue to function normally. The device must be rebooted manually to recover. However, user traffic would not be impacted and could be managed using a remote application such as Cisco Adaptive Security Device Manager (ASDM).
