CVE-2024-21617 – Junos OS: BGP flap on NSR-enabled devices causes memory leak
https://notcve.org/view.php?id=CVE-2024-21617
12 Jan 2024 — An Incomplete Cleanup vulnerability in Nonstop active routing (NSR) component of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker to cause memory leak leading to Denial of Service (DoS). On all Junos OS platforms, when NSR is enabled, a BGP flap will cause memory leak. A manual reboot of the system will restore the services. Note: NSR is not supported on the SRX Series and is therefore not affected by this vulnerability. The memory usage can be monitored using the below commands. user@... • https://supportportal.juniper.net/JSA75758 • CWE-459: Incomplete Cleanup •

CVE-2024-21616 – Junos OS: MX Series and SRX Series: Processing of a specific SIP packet causes NAT IP allocation to fail
https://notcve.org/view.php?id=CVE-2024-21616
12 Jan 2024 — An Improper Validation of Syntactic Correctness of Input vulnerability in Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On all Junos OS MX Series and SRX Series platforms, when SIP ALG is enabled, and a specific SIP packet is received and processed, NAT IP allocation fails for genuine traffic, which causes Denial of Service (DoS). Continuous receipt of this specific SIP ALG packet will cause a sustained DoS con... • https://supportportal.juniper.net/JSA75757 • CWE-1286: Improper Validation of Syntactic Correctness of Input •

CVE-2024-21612 – Junos OS Evolved: Specific TCP traffic causes OFP core and restart of RE
https://notcve.org/view.php?id=CVE-2024-21612
12 Jan 2024 — An Improper Handling of Syntactically Invalid Structure vulnerability in Object Flooding Protocol (OFP) service of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). On all Junos OS Evolved platforms, when specific TCP packets are received on an open OFP port, the OFP crashes leading to a restart of Routine Engine (RE). Continuous receipt of these specific TCP packets will lead to a sustained Denial of Service (DoS) condition. This issue a... • https://supportportal.juniper.net/JSA75753 • CWE-228: Improper Handling of Syntactically Invalid Structure •

CVE-2024-21607 – Junos OS: MX Series and EX9200 Series: If the "tcp-reset" option used in an IPv6 filter, matched packets are accepted instead of rejected
https://notcve.org/view.php?id=CVE-2024-21607
12 Jan 2024 — An Unsupported Feature in the UI vulnerability in Juniper Networks Junos OS on MX Series and EX9200 Series allows an unauthenticated, network-based attacker to cause partial impact to the integrity of the device. If the "tcp-reset" option is added to the "reject" action in an IPv6 filter which matches on "payload-protocol", packets are permitted instead of rejected. This happens because the payload-protocol match criteria is not supported in the kernel filter causing it to accept all packets without taking ... • https://supportportal.juniper.net/JSA75748 • CWE-447: Unimplemented or Unsupported Feature in UI •

CVE-2024-21606 – Junos OS: SRX Series: When "tcp-encap" is configured and specific packets are received flowd will crash
https://notcve.org/view.php?id=CVE-2024-21606
12 Jan 2024 — A Double Free vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). In a remote access VPN scenario, if a "tcp-encap-profile" is configured and a sequence of specific packets is received, a flowd crash and restart will be observed. This issue affects Juniper Networks Junos OS on SRX Series: * All versions earlier than 20.4R3-S8; * 21.2 versions earlier than 21.2R3-S6; * 21.3 versions... • https://supportportal.juniper.net/JSA75747 • CWE-415: Double Free •

CVE-2024-21604 – Junos OS Evolved: A high rate of specific traffic will cause a complete system outage
https://notcve.org/view.php?id=CVE-2024-21604
12 Jan 2024 — An Allocation of Resources Without Limits or Throttling vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). If a high rate of specific valid packets are processed by the routing engine (RE) this will lead to a loss of connectivity of the RE with other components of the chassis and thereby a complete and persistent system outage. Please note that a carefully designed lo0 firewall filter will block or limit thes... • https://supportportal.juniper.net/JSA75745 • CWE-770: Allocation of Resources Without Limits or Throttling •

12 Jan 2024 — A Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in the Flow-processing Daemon (flowd) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (Dos). On SRX Series devices when two different threads try to simultaneously process a queue which is used for TCP events flowd will crash. One of these threads can not be triggered externally, so the exploitation of this race condition is out... • https://supportportal.juniper.net/JSA75742 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
