Summary
Junos OS is prone to a Denial of Service vulnerability with IPv6 enabled.
Insight
Insight
By flooding a router with specially crafted IPv6 traffic, all available resources can be consumed, leading to the inability to store next hop information for legitimate traffic. In extreme cases, the crafted IPv6 traffic may result in a total resource exhaustion and kernel panic. The issue is triggered by traffic destined to the router. Transit traffic does not trigger the vulnerability.
