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.

CVSS: 7.5EPSS: 0%CPEs: 150EXPL: 1CVE-2023-22415 – Junos OS: MX Series and SRX Series: The flow processing daemon (flowd) will crash when specific H.323 packets are received
https://notcve.org/view.php?id=CVE-2023-22415
An Out-of-Bounds Write vulnerability in the H.323 ALG of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On all MX Series and SRX Series platform, when H.323 ALG is enabled and specific H.323 packets are received simultaneously, a flow processing daemon (flowd) crash will occur. Continued receipt of these specific packets will cause a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS on MX Series and SRX Series All versions prior to 19.4R3-S10; 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-S4; 21.2 versions prior to 21.2R3-S3; 21.3 versions prior to 21.3R3-S3; 21.4 versions prior to 21.4R3; 22.1 versions prior to 22.1R2-S1, 22.1R3; 22.2 versions prior to 22.2R1-S2, 22.2R2. Una vulnerabilidad de escritura fuera de los límites en el ALG H.323 de Juniper Networks Junos OS permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS). • https://kb.juniper.net/JSA70211 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 11EXPL: 0CVE-2023-22401 – Junos OS and Junos OS Evolved: PTX10008, PTX10016: When a specific SNMP MIB is queried the FPC will crash
https://notcve.org/view.php?id=CVE-2023-22401
An Improper Validation of Array Index vulnerability in the Advanced Forwarding Toolkit Manager daemon (aftmand) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). On the PTX10008 and PTX10016 platforms running Junos OS or Junos OS Evolved, when a specific SNMP MIB is queried this will cause a PFE crash and the FPC will go offline and not automatically recover. A system restart is required to get the affected FPC in an operational state again. This issue affects: Juniper Networks Junos OS 22.1 version 22.1R2 and later versions; 22.1 versions prior to 22.1R3; 22.2 versions prior to 22.2R2. Juniper Networks Junos OS Evolved 21.3-EVO version 21.3R3-EVO and later versions; 21.4-EVO version 21.4R1-S2-EVO, 21.4R2-EVO and later versions prior to 21.4R2-S1-EVO; 22.1-EVO version 22.1R2-EVO and later versions prior to 22.1R3-EVO; 22.2-EVO versions prior to 22.2R1-S1-EVO, 22.2R2-EVO. • https://kb.juniper.net/JSA70197 • CWE-129: Improper Validation of Array Index •
CVSS: 6.5EPSS: 0%CPEs: 154EXPL: 0CVE-2023-22404 – Junos OS: SRX Series and MX Series with SPC3: When IPsec VPN is configured iked will core when a specifically formatted payload is received
https://notcve.org/view.php?id=CVE-2023-22404
An Out-of-bounds Write vulnerability in the Internet Key Exchange Protocol daemon (iked) of Juniper Networks Junos OS on SRX series and MX with SPC3 allows an authenticated, network-based attacker to cause a Denial of Service (DoS). iked will crash and restart, and the tunnel will not come up when a peer sends a specifically formatted payload during the negotiation. This will impact other IKE negotiations happening at the same time. Continued receipt of this specifically formatted payload will lead to continuous crashing of iked and thereby the inability for any IKE negotiations to take place. Note that this payload is only processed after the authentication has successfully completed. So the issue can only be exploited by an attacker who can successfully authenticate. • https://kb.juniper.net/JSA70200 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 63EXPL: 0CVE-2023-22408 – Junos OS: SRX 5000 Series: Upon processing of a specific SIP packet an FPC can crash
https://notcve.org/view.php?id=CVE-2023-22408
An Improper Validation of Array Index vulnerability in the SIP ALG of Juniper Networks Junos OS on SRX 5000 Series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). When an attacker sends an SIP packets with a malformed SDP field then the SIP ALG can not process it which will lead to an FPC crash and restart. Continued receipt of these specific packets will lead to a sustained Denial of Service. This issue can only occur when both below mentioned conditions are fulfilled: 1. Call distribution needs to be enabled: [security alg sip enable-call-distribution] 2. • https://kb.juniper.net/JSA70204 • CWE-129: Improper Validation of Array Index •
