An Incorrect Behavior Order in the routing engine (RE) of Juniper Networks Junos OS on EX4300 Series allows traffic intended to the device to reach the RE instead of being discarded when the discard term is set in loopback (lo0) interface. The intended function is that the lo0 firewall filter takes precedence over the revenue interface firewall filter.
This issue affects only IPv6 firewall filter.
This issue only affects the EX4300 switch. No other products or platforms are affected by this vulnerability.
This issue affects Juniper Networks Junos OS:
* All versions before 20.4R3-S10,
* from 21.2 before 21.2R3-S7,
* from 21.4 before 21.4R3-S6.

An Access of Memory Location After End of Buffer vulnerability in the Layer-2 Control Protocols Daemon (l2cpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause Denial of Service (DoS).
On all Junos OS and Junos OS Evolved platforms, when LLDP is enabled on a specific interface, and a malformed LLDP packet is received, l2cpd crashes and restarts. The impact of the l2cpd crash is reinitialization of STP protocols (RSTP, MSTP or VSTP), and MVRP and ERP. Also, if any services depend on LLDP state (like PoE or VoIP device recognition), then these will also be affected.
This issue affects:
Junos OS:
* from 21.4 before 21.4R3-S4,
* from 22.1 before 22.1R3-S4,
* from 22.2 before 22.2R3-S2,
* from 22.3 before 22.3R2-S2, 22.3R3-S1,
* from 22.4 before 22.4R3,
* from 23.2 before 23.2R2.
Junos OS Evolved:
* from 21.4-EVO before 21.4R3-S5-EVO,
* from 22.1-EVO before 22.1R3-S4-EVO,
* from 22.2-EVO before 22.2R3-S2-EVO,

* from 22.4-EVO before 22.4R3-EVO,
* from 23.2-EVO before 23.2R2-EVO.
This issue does not affect:
* Junos OS versions prior to 21.4R1;
* Junos OS Evolved versions prior to 21.4R1-EVO.

An Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Juniper Networks Paragon Active Assurance Control Center allows a network-adjacent attacker with root access to a Test Agent Appliance the ability to access sensitive information about downstream devices.
The "netrounds-probe-login" daemon (also called probe_serviced) exposes functions where the Test Agent (TA) Appliance pushes interface state/config, unregister itself, etc. The remote service accidentally exposes an internal database object that can be used for direct database access on the Paragon Active Assurance Control Center.
This issue affects Paragon Active Assurance: 4.1.0, 4.2.0.

A Stack-based Buffer Overflow vulnerability in the Routing Protocol Daemon (RPD) component of Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause an rpd crash, leading to Denial of Service (DoS).
On all Junos OS and Junos OS Evolved platforms, when EVPN is configured, and a specific EVPN type-5 route is received via BGP, rpd crashes and restarts. Continuous receipt of this specific route will lead to a sustained Denial of Service (DoS) condition.
This issue affects:

An Improper Check or Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).
If an attacker sends a specific MPLS packet, which upon processing, causes an internal loop, that leads to a PFE crash and restart. Continued receipt of these packets leads to a sustained Denial of Service (DoS) condition.
Circuit cross-connect (CCC) needs to be configured on the device for it to be affected by this issue.
This issue only affects MX Series with MPC10, MPC11, LC9600, and MX304.
