https://notcve.org/view.php?id=CVE-2023-22407
An Incomplete Cleanup vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS). An rpd crash can occur when an MPLS TE tunnel configuration change occurs on a directly connected router. This issue affects: Juniper Networks Junos OS All versions prior to 18.4R2-S7; 19.1 versions prior to 19.1R3-S2; 19.2 versions prior to 19.2R3; 19.3 versions prior to 19.3R3; 19.4 versions prior to 19.4R3; 20.1 versions prior to 20.1R2; 20.2 versions prior to 20.2R2.

CVSS: 6.5EPSS: 0%CPEs: 130EXPL: 0CVE-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
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 memory consumption can be monitored using the CLI command "show task memory detail" as shown in the following example: user@host> show task memory detail | match "RT_NEXTHOPS_TEMPLATE|RT_TEMPLATE_BOOK_KEE" RT_NEXTHOPS_TEMPLATE 1008 1024 T 50 51200 50 51200 RT_NEXTHOPS_TEMPLATE 688 768 T 50 38400 50 38400 RT_NEXTHOPS_TEMPLATE 368 384 T 412330 158334720 412330 158334720 RT_TEMPLATE_BOOK_KEE 2064 2560 T 33315 85286400 33315 85286400 user@host> show task memory detail | match "RT_NEXTHOPS_TEMPLATE|RT_TEMPLATE_BOOK_KEE" RT_NEXTHOPS_TEMPLATE 1008 1024 T 50 51200 50 51200 RT_NEXTHOPS_TEMPLATE 688 768 T 50 38400 50 38400 RT_NEXTHOPS_TEMPLATE 368 384 T 419005 160897920 419005 160897920 <=== RT_TEMPLATE_BOOK_KEE 2064 2560 T 39975 102336000 39975 10233600 <=== This issue affects: Juniper Networks Junos OS All versions prior to 19.3R3-S7; 19.4 versions prior to 19.4R2-S8, 19.4R3-S9; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S3; 21.2 versions prior to 21.2R3-S2; 21.3 versions prior to 21.3R3-S1; 21.4 versions prior to 21.4R2-S1, 21.4R3; 22.1 versions prior to 22.1R2.

https://notcve.org/view.php?id=CVE-2023-22403
An Allocation of Resources Without Limits or Throttling vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). On QFX10K Series, Inter-Chassis Control Protocol (ICCP) is used in MC-LAG topologies to exchange control information between the devices in the topology. ICCP connection flaps and sync issues will be observed due to excessive specific traffic to the local device. This issue affects Juniper Networks Junos OS on QFX10K Series: * All versions prior to 20.2R3-S7; * 20.4 versions prior to 20.4R3-S4; * 21.1 versions prior to 21.1R3-S3; * 21.2 versions prior to 21.2R3-S1; * 21.3 versions prior to 21.3R3; * 21.4 versions prior to 21.4R3; * 22.1 versions prior to 22.1R2. • https://kb.juniper.net/JSA70199 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 0%CPEs: 172EXPL: 0CVE-2023-22394 – Junos OS: SRX Series and MX Series: Memory leak due to receipt of specially crafted SIP calls
https://notcve.org/view.php?id=CVE-2023-22394
An Improper Handling of Unexpected Data Type vulnerability in the handling of SIP calls in Juniper Networks Junos OS on SRX Series and MX Series platforms allows an attacker to cause a memory leak leading to Denial of Services (DoS). This issue occurs on all MX Series platforms with MS-MPC or MS-MIC card and all SRX Series platforms where SIP ALG is enabled. Successful exploitation of this vulnerability prevents additional SIP calls and applications from succeeding. The SIP ALG needs to be enabled, either implicitly / by default or by way of configuration. To confirm whether SIP ALG is enabled on SRX use the following command: user@host> show security alg status | match sip SIP : Enabled This issue affects Juniper Networks Junos OS on SRX Series and on MX Series: All versions prior to 19.3R3-S7; 19.4 versions prior to 19.4R2-S8, 19.4R3-S10; 20.1 versions 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S6; 20.3 versions prior to 20.3R3-S6; 20.4 versions prior to 20.4R3-S5; 21.1 versions prior to 21.1R3-S5; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2-S2, 21.4R3; 22.1 versions prior to 22.1R1-S2, 22.1R2, 22.1R3-S1. • https://kb.juniper.net/JSA70190 • CWE-911: Improper Update of Reference Count •
CVSS: 6.5EPSS: 0%CPEs: 124EXPL: 0CVE-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
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 monitored by using the CLI command 'show system buffers': user@host> show system buffers 783/1497/2280 mbufs in use (current/cache/total) user@host> show system buffers 793/1487/2280 mbufs in use (current/cache/total) <<<<<< mbuf usage increased This issue affects Juniper Networks Junos OS: All versions prior to 19.3R3-S7; 19.4 versions prior to 19.4R3-S9; 20.1 version 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S3; 21.2 versions prior to 21.2R3-S2; 21.3 versions prior to 21.3R3-S1; 21.4 versions prior to 21.4R3; 22.1 versions prior to 22.1R2.
