VectorAV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Junos OS versions prior to 22.2R3-S4 Junos OS versions 22.4 prior to 22.4R3-S2 Junos OS versions 23.2 prior to 23.2R2 Junos OS versions 23.4 prior to 23.4R2 Junos OS Evolved versions prior to 22.2R3-S4-EVO Junos OS Evolved versions 22.4-EVO prior to 22.4R3-S2-EVO Junos OS Evolved versions 23.2-EVO prior to 23.2R2-EVO Junos OS Evolved versions 23.4-EVO prior to 23.4R2-EVO
Description: An Expired Pointer Dereference issue in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause Denial of Service (DoS). When an MPLS Label-Switched Path (LSP) is configured with node-link-protection and transport-class, and an LSP flaps, rpd crashes and restarts. Continuous flapping of LSP can cause a sustained Denial of Service (DoS) condition.
Recommendations: For Junos OS versions prior to 22.2R3-S4, update to version 22.2R3-S4 or later. For Junos OS versions 22.4 prior to 22.4R3-S2, update to version 22.4R3-S2 or later. For Junos OS versions 23.2 prior to 23.2R2, update to version 23.2R2 or later. For Junos OS versions 23.4 prior to 23.4R2, update to version 23.4R2 or later. For Junos OS Evolved versions prior to 22.2R3-S4-EVO, update to version 22.2R3-S4-EVO or later. For Junos OS Evolved versions 22.4-EVO prior to 22.4R3-S2-EVO, update to version 22.4R3-S2-EVO or later. For Junos OS Evolved versions 23.2-EVO prior to 23.2R2-EVO, update to version 23.2R2-EVO or later. For Junos OS Evolved versions 23.4-EVO prior to 23.4R2-EVO, update to version 23.4R2-EVO or later.
