Description
<br />
An Incomplete Cleanup vulnerability in Nonstop active routing (NSR) component of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker to cause memory leak leading to Denial of Service (DoS).<br />
<br />
On all Junos OS platforms, when NSR is enabled, a BGP flap will cause memory leak. A manual reboot of the system will restore the services.<br />
<br />
Note: NSR is not supported on the SRX Series and is therefore not affected by this vulnerability.<br />
The memory usage can be monitored using the below commands.<br />
<br />
user@host> show chassis routing-engine no-forwarding<br />
user@host> show system memory | no-more<br />
