CVE-2025-52964

Description

A Reachable Assertion 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). When the device receives a specific BGP UPDATE packet, the rpd crashes and restarts. Continuous receipt of this specific packet will cause a sustained DoS condition. For the issue to occur, BGP multipath with "pause-computation-during-churn" must be configured on the device, and the attacker must send the paths via a BGP UPDATE from a established BGP peer. This issue affects: Junos OS: * All versions before 21.4R3-S7, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S5, * from 23.2 before 23.2R2, * from 23.4 before 23.4R2. Junos OS Evolved: * All versions before 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, * from 23.4 before 23.4R2-EVO.
