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.

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. While this issue affects systems running 32-bit and 64-bit systems, the probability of impact on 64-bit system is extremely low. According to KB25803 https://supportportal.juniper.net/s/article/Junos-How-to-check-if-Junos-OS-is-64-or-32-bit-on-a-router , customers can confirm 32-bit or 64-bit system via the ' show version detail ' command: lab@router> show version detail| match 32 JUNOS 32-bit kernel Software Suite lab@router> s
