12 Jan 2024 — A Missing Release of Memory after Effective Lifetime vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause an rpd crash, leading to Denial of Service (DoS). On all Junos OS and Junos OS Evolved platforms, when traffic engineering is enabled for OSPF or ISIS, and a link flaps, a patroot memory leak is observed. This memory leak, over time, will lead to an rpd crash and restart. The memory usage can be monitored u... • https://supportportal.juniper.net/JSA75754 • CWE-401: Missing Release of Memory after Effective Lifetime •

CVE-2024-21612 – Junos OS Evolved: Specific TCP traffic causes OFP core and restart of RE

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 •
