Null pointer dereference
A NULL Pointer Dereference vulnerability in Juniper Networks Junos OS allows an attacker to send a specific packet causing the packet forwarding engine PFE to crash and restart, resulting in a Denial of Service DoS. By continuously sending these specific packets, an attacker can repeatedly disabl...
Memory corruption
On Juniper Networks Junos EX series, QFX Series, MX Series and SRX branch series devices, a memory leak occurs every time the 802.1X authenticator port interface flaps which can lead to other processes, such as the pfex process, responsible for packet forwarding, to crash and restart. An...
Command injection
A command injection vulnerability in install package validation subsystem of Juniper Networks Junos OS that may allow a locally authenticated attacker with privileges to execute commands with root privilege. To validate a package in Junos before installation, an administrator executes the command...
Command injection
A command injection vulnerability in the license-check daemon of Juniper Networks Junos OS that may allow a locally authenticated attacker with low privileges to execute commands with root privilege. license-check is a daemon used to manage licenses in Junos OS. To update licenses, a user execute...
Design/Logic Flaw
In an EVPN/VXLAN scenario, if an IRB interface with a virtual gateway address VGA is configured on a PE, a traffic loop may occur upon receipt of specific IP multicast traffic. The traffic loop will cause interface traffic to increase abnormally, ultimately leading to a Denial of Service DoS in...
Privilege escalation
A local privilege escalation vulnerability in telnetd.real of Juniper Networks Junos OS may allow a locally authenticated shell user to escalate privileges and execute arbitrary commands as root. telnetd.real is shipped with setuid permissions enabled and is owned by the root user, allowing local...
