CVE-2021-0222
CVE-2021-0222 is a Denial of Service (DoS) vulnerability in Juniper Networks Junos OS. The issue arises when an adjacent device sends crafted IPv4/IPv6 protocol packets with invalid payloads; these packets are (incorrectly) replicated and sent toward the Routing Engine, leading to an extended DoS...
CVE-2021-0222 Junos OS: Upon receipt of certain protocol packets with invalid payloads a self-propagating Denial of Service may occur.
A vulnerability in Juniper Networks Junos OS allows an attacker to cause a Denial of Service DoS to the device by sending certain crafted protocol packets from an adjacent device with invalid payloads to the device. These crafted packets, which should be discarded, are instead replicated and sent...
