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.
