Name of the Vulnerable Software and Affected Versions Junos OS on MX Series versions prior to 21.4R3-S9 Junos OS on MX Series versions 22.2 through 22.2R3-S5 Junos OS on MX Series versions 22.3 through 22.3R3-S4 Junos OS on MX Series versions 22.4 through 22.4R3-S2 Junos OS on MX Series versions 23.2 through 23.2R2-S1 Junos OS on MX Series versions 23.4 through 23.4R2
Description A NULL Pointer Dereference issue in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS allows a local, low-privileged attacker to cause a Denial-of-Service (DoS). When a specific command is executed, the pfe crashes, interrupting traffic forwarding until the system self-recovers. Repeated execution will create a sustained DoS condition. This issue only affects MX Series devices with Line cards MPC1-MPC9.
Recommendations For versions prior to 21.4R3-S9, update to version 21.4R3-S9 or later. For versions 22.2 through 22.2R3-S5, update to version 22.2R3-S5 or later. For versions 22.3 through 22.3R3-S4, update to version 22.3R3-S4 or later. For versions 22.4 through 22.4R3-S2, update to version 22.4R3-S2 or later. For versions 23.2 through 23.2R2-S1, update to version 23.2R2-S1 or later. For versions 23.4 through 23.4R2, update to version 23.4R2 or later.
