Detailsinfo

A vulnerability classified as problematic has been found in Juniper Junos (Router Operating System) (the affected version is unknown). This affects an unknown code of the component vmcore. The manipulation as part of a IPv6 Packet leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

Receipt of a specific link-local IPv6 packet destined to the RE may cause the system to crash and restart (vmcore). By continuously sending a specially crafted IPv6 packet, an attacker can repeatedly crash the system causing a prolonged Denial of Service (DoS). This issue affects Juniper Networks Junos OS: 16.1 versions prior to 16.1R6-S2, 16.1R7; 16.2 versions prior to 16.2R2-S10; 17.1 versions prior to 17.1R3.
