Description

An Uncontrolled Resource Consumption vulnerability in the H.323 ALG (Application Layer Gateway) of  Juniper Networks Junos OS on SRX Series and MX Series with SPC3 and MS-MPC/MIC, allows an unauthenticated network-based attacker to send specific packets causing traffic loss leading to Denial of Service (DoS). 

Continued receipt and processing of these specific packets will sustain the Denial of Service condition.

The memory usage can be monitored using the below command.
