Buffer overflow

A buffer size validation vulnerability in the overlayd service of Juniper Networks Junos OS may allow an unauthenticated remote attacker to send specially crafted packets to the device, triggering a partial Denial of Service DoS condition, or leading to remote code execution RCE. Continued receip...

Design/Logic Flaw

A vulnerability in the processing of traffic matching a firewall filter containing a syslog action in Juniper Networks Junos OS on MX Series with MPC10/MPC11 cards installed, PTX10003 and PTX10008 Series devices, will cause the line card to crash and restart, creating a Denial of Service DoS...

Double free

A Double Free vulnerability in the software forwarding interface daemon sfid process of Juniper Networks Junos OS allows an adjacently-connected attacker to cause a Denial of Service DoS by sending a crafted ARP packet to the device. Continued receipt and processing of the crafted ARP packets wil...

Race condition

A signal handler race condition exists in the Layer 2 Address Learning Daemon L2ALD of Juniper Networks Junos OS due to the absence of a specific protection mechanism to avoid a race condition which may allow an attacker to bypass the storm-control feature on devices. This issue is a corner case...
