CVE-2017-10619 is a vulnerability of currently unknown severity. When Express Path (formerly known as service offloading) is configured on Juniper Networks SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800 in high availability cluster configuration mode, certain multicast packets might cause the flowd process to crash, halting or interrupting traffic from flowing through the device and triggering RG1+ (data-plane) fail-over to the secondary node. Repeated crashes of the flowd process may constitute an extended denial of service condition. EPSS estimates a 1.30% chance of exploitation in the next 30 days.

Description

When Express Path (formerly known as service offloading) is configured on Juniper Networks SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800 in high availability cluster configuration mode, certain multicast packets might cause the flowd process to crash, halting or interrupting traffic from flowing through the device and triggering RG1+ (data-plane) fail-over to the secondary node. Repeated crashes of the flowd process may constitute an extended denial of service condition. This service is not enabled by default and is only supported in high-end SRX platforms. Affected releases are Juniper Networks Junos OS 12.3X48 prior to 12.3X48-D45, 15.1X49 prior to 15.1X49-D80 on SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800.
