Severity ?

7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Details

An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause Denial of Service (DoS).

When a BGP UPDATE with malformed path attribute is received over an established BGP session, rpd crashes and restarts.

Continuous receipt of a BGP UPDATE with a specifically malformed path attribute will create a sustained Denial of Service (DoS) condition for impacted devices.

This issue affects:

Juniper Networks Junos OS:

All versions before 21.4R3-S8,
from 22.2 before 22.2R3-S4,
from 22.4 before 22.4R3-S3,
from 23.2 before 23.2R2-S1,
from 23.4 before 23.4R1-S2, 23.4R2.

Juniper Networks Junos OS Evolved:

All versions before 21.4R3-S8-EVO,
from 22.2 before 22.2R3-S4-EVO,
from 22.4 before 22.4R3-S3-EVO,
from 23.2 before 23.2R2-S1-EVO,
from 23.4 before 23.4R1-S2-EVO, 23.4R2-EVO.
