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 , 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
