Details

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.

To identify the issue, execute the CLI command:

user@device> show platform application-info allocations app l2ald-agent EVL Object Allocation Statistics:

Node Application Context Name Live Allocs Fails Guids re0 l2ald-agent net::juniper::rtnh::L2Rtinfo 1069096 1069302 0 1069302 re0 l2ald-agent net::juniper::rtnh::NHOpaqueTlv 114 195 0 195

This issue affects Junos OS Evolved:

All versions before 21.4R3-S8-EVO,
from 22.2-EVO before 22.2R3-S4-EVO,
from 22.3-EVO before 22.3R3-S3-EVO,
from 22.4-EVO before 22.4R3-EVO,
from 23.2-EVO before 23.2R2-EVO.
