Description
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. 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> show version detail| match 64
JUNOS 64-bit kernel Software Suite
