漏洞描述
中文描述:
Cisco Email Security Appliance(ESA)和Cisco AsyncOS都是美国思科(Cisco)公司的产品。Cisco Email Security Appliance是一个电子邮件安全设备。Cisco AsyncOS是一款应用于思科设备的操作系统。 Cisco Email Security Appliance和Cisco AsyncOS存在信任管理问题漏洞,该漏洞源于对受影响设备处理的某些 TLS 连接处理不当。
英文描述:
A vulnerability in Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain TLS connections that are processed by an affected device. An attacker could exploit this vulnerability by establishing a large number of concurrent TLS connections to an affected device. A successful exploit could allow the attacker to cause the device to drop new TLS email messages that come from the associated email servers. Exploitation of this vulnerability does not cause the affected device to unexpectedly reload. The device will recover autonomously within a few hours of when the attack is halted or mitigated.
