CVSS: 8.7EPSS: 0%CPEs: 12EXPL: 0CVE-2024-39515 – Junos OS and Junos OS Evolved: With BGP traceoptions enabled, receipt of specifically malformed BGP update causes RPD crash
https://notcve.org/view.php?id=CVE-2024-39515
An Improper Validation of Consistency within Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker sending a specifically malformed BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. In some cases, rpd fails to restart requiring a manual restart via the 'restart routing' CLI command. This issue only affects systems with BGP traceoptions enabled and requires a BGP session to be already established. Systems without BGP traceoptions enabled are not affected by this issue. This issue affects iBGP and eBGP, and both IPv4 and IPv6 are affected by this vulnerability. This issue affects: Junos OS: * All versions before 21.4R3-S8, * 22.2 before 22.2R3-S5, * 22.3 before 22.3R3-S4, * 22.4 before 22.4R3-S3, * 23.2 before 23.2R2-S2, * 23.4 before 23.4R2; Junos OS Evolved: * All versions before 21.4R3-S8-EVO, * 22.2-EVO before 22.2R3-S5-EVO, * 22.3-EVO before 22.3R3-S4-EVO, * 22.4-EVO before 22.4R3-S3-EVO, * 23.2-EVO before 23.2R2-S2-EVO, * 23.4-EVO before 23.4R2-EVO. • https://supportportal.juniper.net/JSA88099 https://www.juniper.net/documentation/us/en/software/junos/cli-reference/topics/ref/statement/traceoptions-edit-protocols-bgp.html • CWE-1288: Improper Validation of Consistency within Input •
CVSS: 8.7EPSS: 0%CPEs: 18EXPL: 0CVE-2024-39552 – Junos OS and Junos OS Evolved: Malformed BGP UPDATE causes RPD crash
https://notcve.org/view.php?id=CVE-2024-39552
An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a network based, unauthenticated attacker to cause the RPD process to crash leading to a Denial of Service (DoS). When a malformed BGP UPDATE packet is received over an established BGP session, RPD crashes and restarts. Continuous receipt of the malformed BGP UPDATE messages will create a sustained Denial of Service (DoS) condition for impacted devices. This issue affects eBGP and iBGP, in both IPv4 and IPv6 implementations. This issue requires a remote attacker to have at least one established BGP session. This issue affects: Juniper Networks Junos OS: * All versions earlier than 20.4R3-S9; * 21.2 versions earlier than 21.2R3-S7; * 21.3 versions earlier than 21.3R3-S5; * 21.4 versions earlier than 21.4R3-S6; * 22.1 versions earlier than 22.1R3-S4; * 22.2 versions earlier than 22.2R3-S3; * 22.3 versions earlier than 22.3R3-S2; * 22.4 versions earlier than 22.4R3; * 23.2 versions earlier than 23.2R2.

https://notcve.org/view.php?id=CVE-2024-39550
A Missing Release of Memory after Effective Lifetime vulnerability in the rtlogd process of Juniper Networks Junos OS on MX Series with SPC3 allows an unauthenticated, adjacent attacker to trigger internal events cause ( which can be done by repeated port flaps) to cause a slow memory leak, ultimately leading to a Denial of Service (DoS). Memory can only be recovered by manually restarting rtlogd process. The memory usage can be monitored using the below command. user@host> show system processes extensive | match rtlog This issue affects Junos OS on MX Series with SPC3 line card: * from 21.2R3 before 21.2R3-S8, * from 21.4R2 before 21.4R3-S6, * from 22.1 before 22.1R3-S5, * from 22.2 before 22.2R3-S3, * from 22.3 before 22.3R3-S2, * from 22.4 before 22.4R3-S1, * from 23.2 before 23.2R2, * from 23.4 before 23.4R2.

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).
