VectorAV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Juniper Networks Junos OS versions prior to 19.3R3-S7 Juniper Networks Junos OS versions 19.4 prior to 19.4R2-S8, 19.4R3-S9 Juniper Networks Junos OS versions 20.2 prior to 20.2R3-S5 Juniper Networks Junos OS versions 20.3 prior to 20.3R3-S5 Juniper Networks Junos OS versions 20.4 prior to 20.4R3-S4 Juniper Networks Junos OS versions 21.1 prior to 21.1R3-S3 Juniper Networks Junos OS versions 21.2 prior to 21.2R3-S2 Juniper Networks Junos OS versions 21.3 prior to 21.3R3-S1 Juniper Networks Junos OS versions 21.4 prior to 21.4R2-S1, 21.4R3 Juniper Networks Junos OS versions 22.1 prior to 22.1R2 Juniper Networks Junos OS Evolved versions prior to 20.4R3-S4-EVO Juniper Networks Junos OS Evolved versions 21.4 prior to 21.4R2-S1-EVO, 21.4R3-EVO Juniper Networks Junos OS Evolved versions 22.1 prior to 22.1R2-EVO
Description A Missing Release of Memory after Effective Lifetime issue 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. This will eventually lead to an rpd crash and restart when the memory is full. The memory consumption can be monitored using the CLI command "show task memory detail".
Recommendations As a temporary workaround, consider monitoring the memory consumption using the CLI command "show task memory detail" to detect potential issues. For Juniper Networks Junos OS versions prior to 19.3R3-S7, update to version 19.3R3-S7 or later. For Juniper Networks Junos OS versions 19.4 prior to 19.4R2-S8, 19.4R3-S9, update to version 19.4R2-S8, 19.4R3-S9 or later.
