Name of the Vulnerable Software and Affected Versions Junos OS versions prior to 21.2R3-S8 Junos OS versions 21.4 prior to 21.4R3-S8 Junos OS versions 22.2 prior to 22.2R3-S4 Junos OS versions 22.3 prior to 22.3R3-S3 Junos OS versions 22.4 prior to 22.4R3-S2 Junos OS versions 23.2 prior to 23.2R2-S1 Junos OS versions 23.4 prior to 23.4R1-S2, 23.4R2 Junos OS Evolved versions prior to 21.2R3-S8-EVO Junos OS Evolved versions 21.4 prior to 21.4R3-S8-EVO Junos OS Evolved versions 22.2 prior to 22.2R3-S4-EVO Junos OS Evolved versions 22.3 prior to 22.3R3-S3-EVO Junos OS Evolved versions 22.4 prior to 22.4R3-S2-EVO Junos OS Evolved versions 23.2 prior to 23.2R2-S1-EVO Junos OS Evolved versions 23.4 prior to 23.4R1-S2-EVO, 23.4R2-EVO

Description The issue is related to an improper check for unusual or exceptional conditions in the routing protocol daemon of Juniper Networks Junos OS and Junos OS Evolved. This can be exploited by an unauthenticated, network-based attacker to cause a Denial of Service (DoS). Specifically, if BGP Monitoring Protocol (BMP) is configured with rib-in pre-policy monitoring, receiving a BGP update with a malformed AS PATH attribute over an established BGP session can cause the RPD to crash and restart.
