low complexity
juniper CWE-400
5.0
2021-07-15 CVE-2021-0288 Improper Check for Unusual or Exceptional Conditions vulnerability in Juniper Junos
A vulnerability in the processing of specific MPLS packets in Juniper Networks Junos OS on MX Series and EX9200 Series devices with Trio-based MPCs (Modular Port Concentrators) may cause FPC to crash and lead to a Denial of Service (DoS) condition.
low complexity
juniper CWE-754
3.3
2021-07-15 CVE-2021-0289 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Juniper Junos
When user-defined ARP Policer is configured and applied on one or more Aggregated Ethernet (AE) interface units, a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability between the Device Control Daemon (DCD) and firewall process (dfwd) daemons of Juniper Networks Junos OS allows an attacker to bypass the user-defined ARP Policer.
