Vendor Solution
The following software releases have been updated to resolve this specific issue: 14.1X53-D40, 15.1X53-D55, 15.1X53-D60, 16.1R1, and all subsequent releases.
Vendor Workaround
To decrease the risk of seeing the issue, increase the MAC move limit rate on the device, or to work around the issue until a fix can be taken, remove the MAC move limit from the devices running configuration. These actions may introduce other possible unintended consequences to customer environments and should be evaluated carefully on a case-by-case basis and are not complete mitigations.

EUVD-2018-0830 | QFX and EX Series switches configured to drop traffic when the MAC move limit is exceeded will forward traffic instead of dropping traffic. This can lead to denials of services or other unintended conditions. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D40; 15.1X53 versions prior to 15.1X53-D55; 15.1 versions prior to 15.1R7. |
