Name of the Vulnerable Software and Affected Versions Juniper Networks Junos OS versions 19.4 through 19.4R3-S8 Juniper Networks Junos OS versions 20.2 through 20.2R3-S4 Juniper Networks Junos OS versions 20.3 through 20.3R3-S1 Juniper Networks Junos OS versions 20.4 through 20.4R3 Juniper Networks Junos OS versions 21.1 through 21.1R2 Juniper Networks Junos OS versions 21.2 through 21.2R1-S1 Juniper Networks Junos OS versions 21.2R2 through 21.2R2 Juniper Networks Junos OS version 21.2R3 Juniper Networks Junos OS versions 21.3 through 21.3R1 Juniper Networks Junos OS Evolved versions prior to 20.4R3-S1-EVO Juniper Networks Junos OS Evolved versions 21.1-EVO through 21.1R1-EVO Juniper Networks Junos OS Evolved versions 21.2-EVO through 21.2R1-S1-EVO Juniper Networks Junos OS Evolved versions 21.2R2-EVO through 21.2R2-EVO Juniper Networks Junos OS Evolved version 21.2R3-EVO Juniper Networks Junos OS Evolved versions 21.3-EVO through 21.3R1-EVO

Description The issue is related to errors in memory release and unlimited resource allocation in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved. Exploitation of this issue may allow an attacker to cause a denial of service by executing a specific CLI command. In a high-scaled BGP routing environment with rib-sharding enabled, two issues may occur when executing a specific CLI command: a memory leak issue with rpd and a temporary spike in rpd memory usage during command execution.
