Name of the Vulnerable Software and Affected Versions Junos OS Evolved versions prior to 21.4R3-S8-EVO Junos OS Evolved versions 22.2-EVO through 22.2R3-S4-EVO Junos OS Evolved versions 22.3-EVO through 22.3R3-S3-EVO Junos OS Evolved versions 22.4-EVO through 22.4R3-EVO Junos OS Evolved versions 23.2-EVO through 23.2R2-EVO
Description An Uncontrolled Resource Consumption vulnerability in the Layer 2 Address Learning Daemon (l2ald) of Juniper Networks Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a memory leak, eventually exhausting all system memory, leading to a system crash and Denial of Service (DoS). Certain MAC table updates cause a small amount of memory to leak. Once memory utilization reaches its limit, the issue will result in a system crash and restart.

For Junos OS Evolved versions 22.2-EVO through 22.2R3-S4-EVO, update to version 22.2R3-S4-EVO or later. For Junos OS Evolved versions 22.3-EVO through 22.3R3-S3-EVO, update to version 22.3R3-S3-EVO or later.
