Description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
A Missing Release of Memory after Effective Lifetime vulnerability in the kernel of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS).
In a segment-routing scenario with OSPF as IGP, when a peer interface continuously flaps, next-hop churn will happen and a continuous increase in Routing Protocol Daemon (rpd) memory consumption will be observed.
