https://notcve.org/view.php?id=CVE-2023-22396
12 Jan 2023 — An Uncontrolled Resource Consumption vulnerability in TCP processing on the Routing Engine (RE) of Juniper Networks Junos OS allows an unauthenticated network-based attacker to send crafted TCP packets destined to the device, resulting in an MBUF leak that ultimately leads to a Denial of Service (DoS). The system does not recover automatically and must be manually restarted to restore service. This issue occurs when crafted TCP packets are sent directly to a configured IPv4 or IPv6 interface on the device. ... • https://kb.juniper.net/JSA70192 • CWE-400: Uncontrolled Resource Consumption •

CVE-2023-22406 – Junos OS and Junos OS Evolved: A memory leak which will ultimately lead to an rpd crash will be observed when a peer interface flaps continuously in a Segment Routing scenario using OSPF
https://notcve.org/view.php?id=CVE-2023-22406
12 Jan 2023 — A Missing Release of Memory after Effective Lifetime vulnerability in the kernel of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS). In a segment-routing scenario with OSPF as IGP, when a peer interface continuously flaps, next-hop churn will happen and a continuous increase in Routing Protocol Daemon (rpd) memory consumption will be observed. This will eventually lead to an rpd crash and restart when the memory is full. The memo... • https://kb.juniper.net/JSA70202 • CWE-401: Missing Release of Memory after Effective Lifetime •

CVE-2023-22409 – Junos OS: SRX Series, MX Series with SPC3: When an inconsistent NAT configuration exists and a specific CLI command is issued the SPC will reboot
https://notcve.org/view.php?id=CVE-2023-22409
12 Jan 2023 — An Unchecked Input for Loop Condition vulnerability in a NAT library of Juniper Networks Junos OS allows a local authenticated attacker with low privileges to cause a Denial of Service (DoS). When an inconsistent "deterministic NAT" configuration is present on an SRX, or MX with SPC3 and then a specific CLI command is issued the SPC will crash and restart. Repeated execution of this command will lead to a sustained DoS. Such a configuration is characterized by the total number of port blocks being greater t... • https://kb.juniper.net/JSA70205 • CWE-1284: Improper Validation of Specified Quantity in Input •

CVE-2023-22395 – Junos OS: In an MPLS scenario the processing of specific packets to the device causes a buffer leak and ultimately a loss of connectivity
https://notcve.org/view.php?id=CVE-2023-22395
12 Jan 2023 — A Missing Release of Memory after Effective Lifetime vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). In an MPLS scenario specific packets destined to an Integrated Routing and Bridging (irb) interface of the device will cause a buffer (mbuf) to leak. Continued receipt of these specific packets will eventually cause a loss of connectivity to and from the device, and requires a reboot to recover. These mbufs can be monit... • https://kb.juniper.net/JSA70191 • CWE-401: Missing Release of Memory after Effective Lifetime •

CVE-2023-22394 – Junos OS: SRX Series and MX Series: Memory leak due to receipt of specially crafted SIP calls
