CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability has been found in Juniper Junos (Router Operating System) (version now known) and classified as problematic. This vulnerability affects some unknown processing of the component Routing Engine. The manipulation as part of a LDP Packet leads to a resource management vulnerability. The CWE definition for the vulnerability is CWE-399. As an impact it is known to affect availability. CVE summarizes:

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.
