Name of the Vulnerable Software and Affected Versions: Juniper Networks Junos OS versions prior to 21.4R3-S7, from 22.3 before 22.3R3-S3, from 22.4 before 22.4R3-S5, from 23.2 before 23.2R2, and from 23.4 before 23.4R2. Juniper Networks Junos OS Evolved versions prior to 21.4R3-S7-EVO, from 22.3 before 22.3R3-S3-EVO, from 22.4 before 22.4R3-S5-EVO, from 23.2 before 23.2R2-EVO, and from 23.4 before 23.4R2-EVO.

Description: A Reachable Assertion vulnerability exists in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved. An unauthenticated, network-based attacker can trigger a Denial of Service (DoS) by sending a specific BGP UPDATE packet. The rpd process crashes and restarts upon receiving this packet, leading to a sustained DoS if the packet is sent continuously. The vulnerability requires BGP multipath with “pause-computation-during-churn” to be configured and the paths to be sent via a BGP UPDATE from an established BGP peer.

Recommendations: Juniper Networks Junos OS versions prior to 21.4R3-S7: Upgrade to version 21.4R3-S7 or later. Juniper Networks Junos OS versions from 22.3 before 22.3R3-S3: Upgrade to version 22.3R3-S3 or later. Juniper Networks Junos OS versions from 22.4 before 22.4R3-S5: Upgrade to version 22.4R3-S5 or later. Juniper Networks Junos OS versions from 23.2 before 23.2R2: Upgrade to version 23.2R2 or later. Juniper Networks Junos OS versions from 23.4 before 23.4R2: Upgrade to version 23.4R2 or later. Juniper Networks Junos OS Evolved versions prior to 21.4R3-S7-EVO: Upgrade to version 21.4R3-S7-EVO or later. Juniper Networks Junos OS Evolved versions from 22.3 before 22.3R3-S3-EVO: Upgrade to version 22.3R3-S3-EVO or later. Juniper Networks Junos OS Evolved versions from 22.4 before 22.4R3-S5-EVO: Upgrade to version 22.4R3-S5-EVO or later. Juniper Networks Junos OS Evolved versions from 23.2 before 23.2R2-EVO: Upgrade to version 23.2R2-EVO or later. Juniper Networks Junos OS Evolved versions from 23.4 before 23.4R2-EVO: Upgrade to version 23.4R2-EVO or later.
