Name of the Vulnerable Software and Affected Versions: Junos OS versions prior to 21.2R3-S9 Junos OS versions 21.4 prior to 21.4R3-S10 Junos OS versions 22.2 prior to 22.2R3-S6 Junos OS versions 22.4 prior to 22.4R3 Junos OS versions 23.2 prior to 23.2R1-S2, 23.2R2
Description: An issue in the Sampling Route Record Daemon (SRRD) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). When a device configured for flow-monitoring receives a specific BGP update message, it is correctly processed internally by the routing protocol daemon (rpd), but when it's sent to SRRD it's encoded incorrectly which leads to a crash and momentary interruption of jflow processing until it automatically restarts. This issue does not affect traffic forwarding itself.
Recommendations: For versions prior to 21.2R3-S9, update to 21.2R3-S9 or later. For versions 21.4 prior to 21.4R3-S10, update to 21.4R3-S10 or later. For versions 22.2 prior to 22.2R3-S6, update to 22.2R3-S6 or later. For versions 22.4 prior to 22.4R3, update to 22.4R3 or later. For versions 23.2 prior to 23.2R1-S2, 23.2R2, update to 23.2R1-S2, 23.2R2 or later.
