Vulnerability from github
A Missing Release of Memory after Effective Lifetime vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
In a Juniper Flow Monitoring (jflow) scenario route churn that causes BGP next hops to be updated will cause a slow memory leak and eventually a crash and restart of rpd.
Thread level memory utilization for the areas where the leak occurs can be checked using the below command:
user@host> show task memory detail | match so_in so_in6 28 32 344450 11022400 344760 11032320 so_in 8 16 1841629 29466064 1841734 29467744 This issue affects:
Junos OS
- 21.4 versions earlier than 21.4R3;
- 22.1 versions earlier than 22.1R3;
- 22.2 versions earlier than 22.2R3.
Junos OS Evolved
- 21.4-EVO versions earlier than 21.4R3-EVO;
- 22.1-EVO versions earlier than 22.1R3-EVO;
- 22.2-EVO versions earlier than 22.2R3-EVO.
This issue does not affect:
Juniper Networks Junos OS versions earlier than 21.4R1.
Juniper Networks Junos OS Evolved versions earlier than 21.4R1.
