Description
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;
