On all Junos OS and Junos OS Evolved platforms, in a Multicast only Fast Reroute (MoFRR) scenario, the rpd process can crash when a a specific low privileged CLI command is executed. The rpd crash will impact all routing protocols until the process has automatically been restarted. As the operational state which makes this issue exploitable is outside the attackers control, this issue is considered difficult to exploit. Continued execution of this command will lead to a sustained DoS.

If an SRX is configured in L2 transparent mode the receipt of a specific genuine packet can cause a single Packet Processing Engines (PPE) component of the PFE to run into a loop, which in turn will render the PPE unavailable. Each packet will cause one PPE to get into a loop, leading to a gradual performance degradation until all PPEs are unavailable and all traffic processing stops.

When a BGP update message is received over an established BGP session, and that message contains a specific, optional transitive attribute, this session will be torn down with an update message error. This issue cannot propagate beyond an affected system as the processing error occurs as soon as the update is received. This issue is exploitable remotely as the respective attribute can propagate through unaffected systems and intermediate AS (if any). Continuous receipt of a BGP update containing this attribute will create a sustained Denial of Service (DoS) condition. Some customers have experienced these BGP session flaps which prompted Juniper SIRT to release this advisory out of cycle before fixed releases are widely available as there is an effective workaround.

In a BGP rib sharding scenario, when an attribute of an active BGP route is updated memory will leak. As rpd memory usage increases over time the rpd process will eventually run out of memory, crash, and restart. The memory utilization can be monitored with the following CLI commands: show task memory show system processes extensive | match rpd This issue affects: Juniper Networks Junos OS 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3-S6; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R2.

If the receipt of router advertisements is enabled on an interface and a specifically malformed RA packet is received, memory corruption will happen which leads to an rpd crash. This issue affects: Juniper Networks Junos OS 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S3; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R2.
