New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote device is affected by a denial of service vulnerability.
DescriptionAccording to its self-reported version number and configuration, the remote Juniper Junos SRX series device is affected by a denial of service vulnerability in the flow daemon (flowd) when handling multicast session synchronization. An unauthenticated, adjacent attacker can exploit this issue, by sending specially crafted multicast packets, to cause the flowd daemon to crash and restart.
Note that this vulnerability only occurs in chassis cluster configurations that process transit multicast traffic. Transit multicast traffic is processed on an SRX services gateway by enabling PIM in normal Flow Mode, or via security policies permitting transit multicast traffic in L2/Transparent Mode.
Nessus has not tested for this issue but has instead relied only on the device's self-reported version, model, and current configuration.
