CVE-2018-0032: Junos OS: RPD crash when receiving a crafted BGP UPDATE

The receipt of a crafted BGP UPDATE can lead to a routing process daemon (RPD) crash and restart. Repeated receipt of the same crafted BGP UPDATE can result in an extended denial of service condition for the device. This issue only affects the specific versions of Junos OS listed within this advisory. Earlier releases are unaffected by this vulnerability. This crafted BGP UPDATE does not propagate to other BGP peers. Affected releases are Juniper Networks Junos OS: 16.1X65 versions prior to 16.1X65-D47; 17.2X75 versions prior to 17.2X75-D91, 17.2X75-D110; 17.3 versions prior to 17.3R1-S4, 17.3R2; 17.4 versions prior to 17.4R1-S3, 17.4R2.

Security readout for executives and security teams

A malformed BGP routing message can crash and restart Juniper Junos OS routing software on specific releases. Repeated messages can create an extended denial of service. The issue affects availability, not data confidentiality or integrity, and the source bundle does not show active exploitation. Exposure is most likely on Juniper devices running the listed Junos OS 16.1X65, 17.2X75, 17.3, or 17.4 affected releases with BGP enabled and reachable from peers. Treat as high priority for routing infrastructure. Affected routers can lose routing availability, and repeated messages may sustain disruption. Prioritize devices that support internet, WAN, partner, or customer connectivity. Mitigation focus: Upgrade affected Junos OS releases to the fixed versions listed by Juniper.; Review Juniper JSA10866 for any current vendor guidance or operational mitigations.; Prioritize BGP-speaking edge, transit, and partner-facing routers..
