Detail

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Layer 2 Address Learning Daemon� (l2ald) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).

When telemetry requests are sent to the device,� and the Dynamic Rendering Daemon (drend) is suspended, the l2ald crashes and restarts due to factors outside the attackers control. Repeated occurrences of these events causes a sustained DoS condition.

This issue affects: Junos OS: All versions earlier than� 20.4R3-S10; 21.2 versions earlier than� 21.2R3-S7; 21.4 versions earlier than� 21.4R3-S5; 22.1 versions earlier than� 22.1R3-S4; 22.2 versions earlier than� 22.2R3-S3; 22.3 versions earlier than� 22.3R3-S1; 22.4 versions earlier than� 22.4R3; 23.2 versions earlier than� 23.2R1-S2, 23.2R2.

Junos OS Evolved:

All versions earlier than� 21.4R3-S5-EVO; 22.1-EVO versions earlier than� 22.1R3-S4-EVO; 22.2-EVO versions earlier than� 22.2R3-S3-EVO; 22.3-EVO versions earlier than� 22.3R3-S1-EVO; 22.4-EVO versions earlier than� 22.4R3-EVO; 23.2-EVO versions earlier than� 23.2R2-EVO.
