Description

An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).

  • 22.4 versions before 22.4R3-S1,
  • 23.2 versions before 23.2R2,
  • 23.4 versions before 23.4R1-S1, 23.4R2,

This issue does not affect Junos OS versions earlier than 22.4R1.

Junos OS Evolved:

  • 22.4-EVO versions before 22.4R3-S2-EVO,
  • 23.2-EVO versions before 23.2R2-EVO,
