Vulnerability Title
Junos OS and Junos OS Evolved: Receipt of a specific malformed BGP path attribute leads to an RPD crash
Source: NVD (National Vulnerability Database)
Vulnerability 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  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.
