A malicious network-based packet flood of these crafted IPv6 NDP packets may eventually lead to resource exhaustion and a denial of service. The affected Junos OS versions are: 12.3 prior to 12.3R12-S4, 12.3R13; 13.3 prior to 13.3R10; 14.1 prior to 14.1R8-S3, 14.1R9; 14.1X53 prior ro 14.1X53-D12, 14.1X53-D40; 14.1X55 prior to 14.1X55-D35;
