On Juniper Networks devices running Junos OS affected versions and with LDP enabled, a specific LDP packet destined to the RE (Routing Engine) will consume a small amount of the memory allocated for the rpd (routing protocol daemon) process. Over time, repeatedly receiving this type of LDP packet(s) will cause the memory to exhaust and the rpd process to crash and restart. It is not possible to free up the memory that has been consumed without restarting the rpd process. This issue affects Junos OS based devices with either IPv4 or IPv6 LDP enabled via the [protocols ldp] configuration (the native IPv6 support for LDP is available in Junos OS 16.1 and higher). The interface on which the packet arrives needs to have LDP enabled. The affected Junos versions are: 13.3 prior to 13.3R10; 14.1 prior to 14.1R8; 14.2 prior to 14.2R7-S6 or 14.2R8; 15.1 prior to 15.1F2-S14, 15.1F6-S4, 15.1F7, 15.1R4-S7, 15.1R5; 15.1X49 before 15.1X49-D70; 15.1X53 before 15.1X53-D230, 15.1X53-D63, 15.1X53-D70; 16.1 before 16.1R2. 16.2R1 and all subsequent releases have a resolution for this vulnerability.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.5, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts and availability (service disruption) for affected systems. Impacting 1 product from juniper organizations running these solutions should prioritize assessment and patching.
First disclosed in 2017, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For juniper's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
