CVSS: 8.7EPSS: 0%CPEs: 16EXPL: 0CVE-2024-39549 – Junos OS and Junos OS Evolved: Receipt of malformed BGP path attributes leads to a memory leak
https://notcve.org/view.php?id=CVE-2024-39549
A Missing Release of Memory after Effective Lifetime vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This memory is not properly freed in all circumstances, leading to a Denial of Service (DoS). Consumed memory can be freed by manually restarting Routing Protocol Daemon (rpd). Memory utilization could be monitored by: user@host> show system memory or show system monitor memory status This issue affects: Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S8, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S3, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R1-S2, 23.4R2.

CVSS: 8.7EPSS: 0%CPEs: 9EXPL: 0CVE-2024-39545 – Junos OS: SRX Series, MX Series with SPC3 and NFX350: When VPN tunnels parameters are not configured in specific way the iked process will crash
https://notcve.org/view.php?id=CVE-2024-39545
An Improper Check for Unusual or Exceptional Conditions vulnerability in the the IKE daemon (iked) of Juniper Networks Junos OS on SRX Series, MX Series with SPC3 and NFX350 allows allows an unauthenticated, network-based attacker sending specific mismatching parameters as part of the IPsec negotiation to trigger an iked crash leading to Denial of Service (DoS). This issue is applicable to all platforms that run iked. This issue affects Junos OS on SRX Series, MX Series with SPC3 and NFX350: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S7, * from 22.1 before 22.1R3-S2, * from 22.2 before 22.2R3-S1, * from 22.3 before 22.3R2-S1, 22.3R3, * from 22.4 before 22.4R1-S2, 22.4R2, 22.4R3. • https://supportportal.juniper.net/JSA83007 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2024-39543
A Buffer Copy without Checking Size of Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Juniper Networks Junos OS Evolved allows an unauthenticated, adjacent attacker to send specific RPKI-RTR packets resulting in a crash, creating a Denial of Service (DoS) condition. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue affects Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S8, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R2.

CVSS: 8.7EPSS: 0%CPEs: 6EXPL: 0CVE-2024-39542 – Junos OS and Junos OS Evolved: A malformed CFM packet or specific transit traffic leads to FPC crash
https://notcve.org/view.php?id=CVE-2024-39542
An Improper Validation of Syntactic Correctness of Input vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on MX Series with MPC10/11 or LC9600, MX304, and Junos OS Evolved on ACX Series and PTX Series allows an unauthenticated, network based attacker to cause a Denial-of-Service (DoS). This issue can occur in two scenarios: 1. If a device, which is configured with SFLOW and ECMP, receives specific valid transit traffic, which is subject to sampling, the packetio process crashes, which in turn leads to an evo-aftman crash and causes the FPC to stop working until it is restarted. (This scenario is only applicable to PTX but not to ACX or MX.) 2. If a device receives a malformed CFM packet on an interface configured with CFM, the packetio process crashes, which in turn leads to an evo-aftman crash and causes the FPC to stop working until it is restarted. Please note that the CVSS score is for the formally more severe issue 1. The CVSS score for scenario 2. is: 6.5 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) This issue affects Junos OS: * All versions before 21.2R3-S4, * 21.4 versions before 21.4R2, * 22.2 versions before 22.2R3-S2; Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * 21.4 versions before 21.4R2-EVO. • https://supportportal.juniper.net/JSA83002 • CWE-1286: Improper Validation of Syntactic Correctness of Input •
CVSS: 7.1EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39541 – Junos OS and Junos OS Evolved: Inconsistent information in the TE database can lead to an rpd crash
https://notcve.org/view.php?id=CVE-2024-39541
An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). When conflicting information (IP or ISO addresses) about a node is added to the Traffic Engineering (TE) database and then a subsequent operation attempts to process these, rpd will crash and restart. This issue affects: Junos OS: * 22.4 versions before 22.4R3-S1, * 23.2 versions before 23.2R2, * 23.4 versions before 23.4R1-S1, 23.4R2, This issue does not affect Junos OS versions earlier than 22.4R1. Junos OS Evolved: * 22.4-EVO versions before 22.4R3-S2-EVO, * 23.2-EVO versions before 23.2R2-EVO, * 23.4-EVO versions before 23.4R1-S1-EVO, 23.4R2-EVO, This issue does not affect Junos OS Evolved versions earlier than before 22.4R1. • https://supportportal.juniper.net/JSA83001 • CWE-755: Improper Handling of Exceptional Conditions •
