Description: An Expected Behavior Violation exists in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved. An unauthenticated attacker adjacent to the system can send a valid BGP UPDATE packet, causing a BGP session reset and resulting in a Denial of Service (DoS). Continuous receipt and processing of this packet can create a sustained DoS condition. This issue affects both iBGP and eBGP, and both IPv4 and IPv6.
Recommendations: Update to Junos OS version 21.2R3-S9 or later. Update to Junos OS version 21.4R3-S11 or later. Update to Junos OS version 22.2R3-S7 or later. Update to Junos OS version 22.4R3-S7 or later. Update to Junos OS version 23.2R2-S4 or later. Update to Junos OS version 23.4R2-S4 or later. Update to Junos OS version 24.2R2 or later.
