14 Jul 2023 — An Improper Validation of Specified Index, Position, or Offset in Input vulnerability in the Connectivity Fault Management(CFM) module of Juniper Networks Junos OS on MX Series(except MPC10, MPC11 and LC9600) allows an adjacent attacker on the local broadcast domain to cause a Denial of Service(DoS). Upon receiving a malformed CFM packet, the MPC crashes. Continued receipt of these packets causes a sustained denial of service. This issue can only be triggered when CFM hasn't been configured. This issue affe... • https://supportportal.juniper.net/JSA71661 • CWE-1285: Improper Validation of Specified Index, Position, or Offset in Input •

14 Jul 2023 — An Improper Handling of Undefined Values vulnerability in the periodic packet management daemon (PPMD) of Juniper Networks Junos OS on MX Series(except MPC10, MPC11 and LC9600) allows an unauthenticated adjacent attacker to cause a Denial of Service (DoS). When a malformed CFM packet is received, it leads to an FPC crash. Continued receipt of these packets causes a sustained denial of service. This vulnerability occurs only when CFM has been configured on the interface. This issue affects Juniper Networks J... • https://supportportal.juniper.net/JSA71659 • CWE-232: Improper Handling of Undefined Values •

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 •

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 •

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 •

14 Jul 2023 — An Improper Check or Handling of Exceptional Conditions vulnerability in the UTM (Unified Threat Management) Web-Filtering feature of Juniper Networks Junos OS on SRX Series causes a jbuf memory leak to occur when accessing certain websites, eventually leading to a Denial of Service (DoS) condition. Service restoration is only possible by rebooting the system. The jbuf memory leak only occurs in SSL Proxy and UTM Web-Filtering configurations. Other products, platforms, and configurations are not affected by... • https://supportportal.juniper.net/JSA71636 • CWE-703: Improper Check or Handling of Exceptional Conditions •

21 Jun 2023 — An Improper Input Validation 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 a BGP update message is received over an established BGP session, and that message contains a specific, optional transitive attribute, this session will be torn down with an update message error. This issue cannot propagate beyond an affected system as the processing error occurs as soon as... • https://supportportal.juniper.net/JSA71542 • CWE-20: Improper Input Validation •

17 Apr 2023 — An Improper Check or Handling of Exceptional Conditions vulnerability in packet processing on the network interfaces of Juniper Networks Junos OS on JRR200 route reflector appliances allows an adjacent, network-based attacker sending a specific packet to the device to cause a kernel 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 can only be triggered by an attacker on the local broadcast dom... • https://supportportal.juniper.net/JSA70594 • CWE-703: Improper Check or Handling of Exceptional Conditions CWE-755: Improper Handling of Exceptional Conditions •

17 Apr 2023 — An Unexpected Status Code or Return Value vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated attacker with physical access to the device to cause a Denial of Service (DoS). When certain USB devices are connected to a USB port of the routing-engine (RE), the kernel will crash leading to a reboot of the device. The device will continue to crash as long as the USB device is connected. This issue affects Juniper Networks Junos OS: All versions prior to 19.4R3-S10; 20.2 versions p... • https://supportportal.juniper.net/JSA70600 • CWE-394: Unexpected Status Code or Return Value CWE-754: Improper Check for Unusual or Exceptional Conditions •

17 Apr 2023 — A Use After Free vulnerability in the Layer 2 Address Learning Manager (l2alm) of Juniper Networks Junos OS on QFX Series allows an adjacent attacker to cause the Packet Forwarding Engine to crash and restart, leading to a Denial of Service (DoS). The PFE may crash when a lot of MAC learning and aging happens, but due to a Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization) that is outside the attackers direct control.
