Improper Handling of Exceptional Conditions in Ethernet interface frame processing of Juniper Networks Junos OS allows an attacker to send specially crafted frames over the local Ethernet segment, causing the interface to go into a down state, resulting in a Denial of Service DoS condition. The...

CVE-2021-0295

The CVE-2021-0295 issue affects Juniper Networks Junos OS on QFX10K Series switches (e.g., QFX10002/10008/10016). It’s caused by DVMRP packets looping on a multi-homed ESI when VXLAN is configured, leading to a packet forwarding loop that triggers a partial DoS. Affected versions include multiple...

CVE-2021-0295 Junos OS: QFX10K Series: Denial of Service (DoS) upon receipt of DVMRP packets received on multi-homing ESI in VXLAN.

A vulnerability in the Distance Vector Multicast Routing Protocol DVMRP of Juniper Networks Junos OS on the QFX10K Series switches allows an attacker to trigger a packet forwarding loop, leading to a partial Denial of Service DoS. The issue is caused by DVMRP packets looping on a multi-homed...

CVE-2021-0294

CVE-2021-0294 affects Junos OS 18.4R2-S5 on QFX5000 Series and EX4600 Series; when storm-control enhanced is configured, the enhanced storm control filter group may not be installed, causing storm control to fail and potentially high CPU usage or packet loss from excessive broadcast/unknown unica...

CVE-2021-0294 Junos OS: QFX5000 Series and EX4600 Series: Enhanced storm control might not work leading to partial Denial of Service

A vulnerability in Juniper Networks Junos OS, which only affects the release 18.4R2-S5, where a function is inconsistently implemented on Juniper Networks Junos QFX5000 Series and EX4600 Series, and if "storm-control enhanced" is configured, can lead to the enhanced storm control filter group not...

CVE-2021-0293

CVE-2021-0293 describes a memory leak in Junos OS caused by Missing Release of Memory after Effective Lifetime. Repeated execution of the CLI command 'show system connections extensive' can cause memory to leak per invocation, depending on TCP connections, potentially leading to daemon memory pre...

CVE-2021-0293 Junos OS: Out-of-memory condition and crashes can occur after executing a certain CLI command repeatedly
