QID 317174

A vulnerability in the DNS inspection handler of Cisco Adaptive Security Appliance (ASA) Software
could allow an unauthenticated, remote attacker to cause a denial of service condition (DoS) on an affected device.

Affected Products
Cisco products if they are running a vulnerable release of Cisco ASA Software and have DNS inspection enabled. Vulnerable versions:
Earlier than 9.12.4.38
From 9.13 Prior to 9.14.4
From 9.15 Prior to 9.15.1.21
From 9.16 Prior to 9.16.2.14
From 9.17 Prior to 9.17.1.7

QID Detection Logic (Authenticated):
The check matches Cisco ASA OS version retrieved via Unix Auth using "version" command.

A successful exploit could allow the attacker to cause the device to stop responding, resulting in a DoS condition.
