Name of the Vulnerable Software and Affected Versions Juniper Networks Junos OS versions prior to 18.1R2-S4 Juniper Networks Junos OS version 18.1R3-S1 Juniper Networks Junos OS version 18.1X75

Description A memory leak issue in Juniper Networks Junos OS allows an attacker to cause a Denial of Service (DoS) to the device. This can be achieved by sending specific commands from a peered BGP host, which are then delivered to the vulnerable device.

Recommendations For versions prior to 18.1R2-S4, update to 18.1R2-S4 or later. For version 18.1R3-S1, update to a version later than 18.1R3-S1. For version 18.1X75, consider disabling BGP protocol temporarily until a patch is available. As a temporary workaround, consider restricting access to the BGP protocol to minimize the risk of exploitation.
