CVE-2021-0242

A vulnerability due to the improper handling of direct memory access DMA buffers on EX4300 switches on Juniper Networks Junos OS allows an attacker sending specific unicast frames to trigger a Denial of Service DoS condition by exhausting DMA buffers, causing the FPC to crash and the device to...

Input validation

Improper Handling of Unexpected Data in the firewall policer of Juniper Networks Junos OS on EX4300 switches allows matching traffic to exceed set policer limits, possibly leading to a limited Denial of Service DoS condition. When the firewall policer discard action fails on a Layer 2 port, it wi...

CVE-2021-0243

CVE-2021-0243 affects Juniper Networks Junos OS on the EX4300, where the firewall policer’s discard action can fail on a Layer 2 port, allowing traffic to pass and be forwarded even when policer limits are exceeded. This impacts IPv4 policing (not IPv6 or firewall policing actions) and can manife...

CVE-2021-0242

CVE-2021-0242 describes a DoS vulnerability in Juniper Junos OS on EX4300 switches where processing of DMA buffers can be exhausted by specific valid unicast frames received on an interface without L2PT or dot1x. Affected FPCs may crash and reboot as DMA buffers continually increase, with log ind...

CVE-2019-0048

On EX4300 Series switches with TCAM optimization enabled, incoming multicast traffic matches an implicit loopback filter rule first, since it has high priority. This rule is meant for reserved multicast addresses 224.0.0.x, but incorrectly matches on 224.x.x.x. Due to this bug, when a firewall...

CVE-2016-1260

Juniper Junos OS before 13.2X51-D36, 14.1X53 before 14.1X53-D25, and 15.2 before 15.2R1 on EX4300 series switches allow remote attackers to cause a denial of service network loop and bandwidth consumption via unspecified vectors related to Spanning Tree Protocol STP traffic...
