CVE-2020-1626 – Junos OS Evolved: Denial of Service vulnerability in processing high rate of specific packets
https://notcve.org/view.php?id=CVE-2020-1626
A vulnerability in Juniper Networks Junos OS Evolved may allow an attacker to cause a Denial of Service (DoS) by sending a high rate of specific packets to the device, resulting in a pfemand process crash. The pfemand process is responsible for packet forwarding on the device. By continuously sending the packet flood, an attacker can repeatedly crash the pfemand process causing a sustained Denial of Service. This issue can only be triggered by traffic sent to the device. Transit traffic does not cause this issue. • https://kb.juniper.net/JSA11005 https://tools.ietf.org/html/rfc6192 •
