Description The issue is related to an uncontrolled resource consumption vulnerability in the Routing Protocol Daemon (RPD) in Juniper Networks Junos OS. This vulnerability can be triggered by a specific SNMP request, causing an infinite loop and resulting in a high CPU usage Denial of Service (DoS) condition. The issue affects both SNMP over IPv4 and IPv6.

Recommendations As a temporary workaround, consider disabling the SNMP service until a patch is available. Restrict access to the vulnerable Routing Protocol Daemon (RPD) to minimize the risk of exploitation. Update to a fixed version of Juniper Networks Junos OS for each affected version. For versions 12.3X48, update to 12.3X48-D90 or later. For versions 15.1, update to 15.1R7-S6 or later. For versions 15.1X49, update to 15.1X49-D200 or later. For versions 15.1X53, update to 15.1X53-D238, 15.1X53-D592 or later. For versions 16.1, update to 16.1R7-S5 or later. For versions 16.2, update to 16.2R2-S11 or later. For versions 17.1, update to 17.1R3-S1 or later. For versions 17.2, update to 17.2R3-S2 or later. For versions 17.3, update to 17.3R3-S7 or later. For versions 17.4, update to 17.4R2-S4, 17.4R3 or later. For versions 18.1, update to 18.1R3-S5 or later. For versions 18.2, update to 18.2R3 or later. For versions 18.2X75, update to 18.2X75-D50 or later. For versions 18.3, update to 18.3R2 or later. For versions 18.4, update to 18.4R2 or later. For versions 19.1, update to 19.1R2 or later.
