Cisco Adaptive Security Appliance (ASA) Software (affected versions not specified)
Cisco Firepower Threat Defense (FTD) Software (affected versions not specified)
Description
A vulnerability in the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) handler could allow an unauthenticated, remote attacker to exhaust memory resources on the affected device, leading to a denial of service (DoS) condition. The vulnerability is due to improper resource management for inbound SSL/TLS connections. An attacker could exploit this vulnerability by establishing multiple SSL/TLS connections with specific conditions to the affected device. A successful exploit could allow the attacker to exhaust the memory on the affected device, causing the device to stop accepting new SSL/TLS connections and resulting in a DoS condition for services on the device that process SSL/TLS traffic. Manual intervention is required to recover an affected device.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
