CVE-2017-2347: Junos: Denial of Service vulnerability in rpd daemon

Security readout for executives and security teams

This flaw can make affected Juniper Junos devices lose routing process availability when MPLS OAM is enabled. A malformed MPLS ping packet can crash the rpd daemon, and repeated crashes can create an extended denial of service. The issue is operationally important for networks that rely on affected Junos versions for routing stability. Exposure is limited to listed Junos OS release trains before the named fixed versions, and only where MPLS OAM is configured. The source bundle states no other Juniper Networks products or platforms are affected. Treat this as a moderate availability risk for affected Juniper routing infrastructure. It is not described as data theft or system takeover, but repeated routing daemon crashes can disrupt network operations. Prioritize validation and upgrade planning where MPLS OAM is enabled. Mitigation focus: Upgrade affected Junos OS systems to the fixed releases listed by Juniper or later.; Prioritize devices running MPLS OAM on affected Junos release trains.; Check Juniper JSA10795 for vendor-specific remediation guidance before operational changes..
