CVE-2023-36835 – Junos OS: QFX10000 Series: All traffic will be dropped after a specific valid IP packet has been received which needs to be routed over a VXLAN tunnel
https://notcve.org/view.php?id=CVE-2023-36835
14 Jul 2023 — An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on QFX10000 Series allows a network based attacker to cause a Denial of Service (DoS). If a specific valid IP packet is received and that packet needs to be routed over a VXLAN tunnel, this will result in a PFE wedge condition due to which traffic gets impacted. As this is not a crash and restart scenario, this condition will persist until the system is rebooted to recover... • https://supportportal.juniper.net/JSA71642 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

CVE-2023-36833 – Junos OS Evolved: PTX10001-36MR, and PTX10004, PTX10008, PTX10016 with LC1201/1202: The aftman-bt process will crash in a MoFRR scenario after multiple link flaps
https://notcve.org/view.php?id=CVE-2023-36833
14 Jul 2023 — A Use After Free vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS Evolved on PTX10001-36MR, and PTX10004, PTX10008, PTX10016 with LC1201/1202 allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS). The process 'aftman-bt' will crash after multiple flaps on a multicast-only fast reroute (MoFRR) enabled interface. This will cause the respective FPC to stop forwarding traffic and it needs to be rebooted to restore the service. An indication that the syst... • https://supportportal.juniper.net/JSA71640 • CWE-416: Use After Free •

CVE-2023-36838 – Junos OS: SRX Series: A flowd core occurs when running a low privileged CLI command
https://notcve.org/view.php?id=CVE-2023-36838
14 Jul 2023 — An Out-of-bounds Read vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series allows a local, authenticated attacker with low privileges, to cause a Denial of Service (DoS). If a low privileged user executes a specific CLI command, flowd which is responsible for traffic forwarding in SRX crashes and generates a core dump. This will cause temporary traffic interruption until the flowd process is restarted automatically. Continued execution of this command will lead to a... • https://supportportal.juniper.net/JSA71645 • CWE-125: Out-of-bounds Read •

CVE-2023-36832 – Junos OS: MX Series: PFE crash upon receipt of specific packet destined to an AMS interface
https://notcve.org/view.php?id=CVE-2023-36832
14 Jul 2023 — An Improper Handling of Exceptional Conditions vulnerability in packet processing of Juniper Networks Junos OS on MX Series allows an unauthenticated network-based attacker to send specific packets to an Aggregated Multiservices (AMS) interface on the device, causing the packet forwarding engine (PFE) to crash, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue is only triggered by packets destined to ... • https://supportportal.juniper.net/JSA71639 • CWE-755: Improper Handling of Exceptional Conditions •

CVE-2023-0026 – 2023-06: Out-of-Cycle Security Bulletin: Junos OS and Junos OS Evolved: A BGP session will flap upon receipt of a specific, optional transitive attribute
