An Incorrect Authorization vulnerability in the web server of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to reach the
Juniper Web Device Manager
(J-Web).
When Juniper Secure connect (JSC) is enabled on specific interfaces, or multiple interfaces are configured for J-Web, the J-Web UI is reachable over more than the intended interfaces.

An Improper Resource Shutdown or Release vulnerability in the SIP ALG of Juniper Networks Junos OS on MX Series with MS-MPC allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).
When an MX Series device with an MS-MPC is configured with two or more service sets which are both processing SIP calls, a specific sequence of call events will lead to a crash and restart of the MS-MPC.
This issue affects Junos OS:
* all versions before 21.2R3-S9,
* 21.4 versions from 21.4R1,
* 22.2 versions before 22.2R3-S6,
* 22.4 versions before 22.4R3-S6.
As the MS-MPC is EoL after Junos OS 22.4, later versions are not affected.
This issue does not affect MX-SPC3 or SRX Series devices.

An Incorrect Calculation of Buffer Size vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to cause a memory corruption that leads to a rpd crash.
When
the logical interface using a routing instance flaps continuously, specific updates are sent to the jflow/sflow modules. This results in memory corruption, leading to an rpd crash and restart.
Continued receipt of these specific updates will cause a sustained Denial of Service condition.

* All versions before 21.2R3-S9,
* All versions of 21.4,
* All versions of 22.2,
* from 22.4 before 22.4R3-S7,

A Reachable Assertion vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
When the device receives a specific BGP UPDATE packet, the rpd crashes and restarts. Continuous receipt of this specific packet will cause a sustained DoS condition.
For the issue to occur, BGP multipath with "pause-computation-during-churn" must be configured on the device, and the attacker must send the paths via a BGP UPDATE from a established BGP peer.
This issue affects:
Junos OS:
* All versions before 21.4R3-S7,
* from 22.3 before 22.3R3-S3,
* from 22.4 before 22.4R3-S5,
* from 23.2 before 23.2R2,
* from 23.4 before 23.4R2.

An Improper Handling of Exceptional Conditions vulnerability in route processing of Juniper Networks Junos OS on specific end-of-life (EOL) ACX Series platforms allows an attacker to crash the Forwarding Engine Board (FEB) by flapping an interface, leading to a Denial of Service (DoS).
On ACX1000, ACX1100, ACX2000, ACX2100, ACX2200, ACX4000, ACX5048, and ACX5096 devices, FEB0 will crash when the primary path port of the L2 circuit IGP (Interior Gateway Protocol) on the local device goes down. This issue is seen only when 'hot-standby' mode is configured for the L2 circuit.
This issue affects Junos OS on ACX1000, ACX1100, ACX2000, ACX2100, ACX2200, ACX4000, ACX5048, and ACX5096:
* all versions before 21.2R3-S9.

An Improper Handling of Exceptional Conditions vulnerability in Berkeley Packet Filter (BPF) processing of Juniper Networks Junos OS allows an attacker, in rare cases, sending specific, unknown traffic patterns to cause the FPC and system to crash and restart.
BPF provides a raw interface to data link layers in a protocol independent fashion. Internally within the Junos kernel, due to a rare timing issue (race condition), when a BPF instance is cloned, the newly created interface causes an internal structure leakage, leading to a system crash. The precise content and timing of the traffic patterns is indeterminate, but has been seen in a lab environment multiple times.
This issue is more likely to occur when packet capturing is enabled. See required configuration below.
This issue affects Junos OS:
* all versions before 21.2R3-S9,
* from 21.4 before 21.4R3-S10,
* from 22.2 before 22.2R3-S6,
* from 22.4 before 22.4R3-S7,

* from 23.4 before 23.4R2-S3,
* from 24.2 before 24.2R1-S1, 24.2R2.
