CVSS: 7.4EPSS: 0%CPEs: 320EXPL: 0CVE-2022-22176 – Junos OS: In a scenario with dhcp-security and option-82 configured jdhcpd crashes upon receipt of a malformed DHCP packet
https://notcve.org/view.php?id=CVE-2022-22176
An Improper Validation of Syntactic Correctness of Input vulnerability in the Juniper DHCP daemon (jdhcpd) of Juniper Networks Junos OS allows an adjacent unauthenticated attacker sending a malformed DHCP packet to cause a crash of jdhcpd and thereby a Denial of Service (DoS). If option-82 is configured in a DHCP snooping / -security scenario, jdhcpd crashes if a specific malformed DHCP request packet is received. The DHCP functionality is impacted while jdhcpd restarts, and continued exploitation of the vulnerability will lead to the unavailability of the DHCP service and thereby a sustained DoS. This issue affects Juniper Networks Junos OS 13.2 version 13.2R1 and later versions prior to 15.1R7-S11; 18.3 versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R2-S9, 18.4R3-S10; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R2-S7, 19.3R3-S4; 19.4 versions prior to 19.4R3-S6; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2-S1, 21.1R3; 21.2 versions prior to 21.2R1-S1, 21.2R2. This issue does not affect Juniper Networks Junos OS version 12.3R12 and prior versions. • https://kb.juniper.net/JSA11282 • CWE-20: Improper Input Validation CWE-1286: Improper Validation of Syntactic Correctness of Input •
CVSS: 7.5EPSS: 0%CPEs: 149EXPL: 0CVE-2022-22173 – Junos OS: CRL failing to download causes a memory leak and ultimately a DoS
https://notcve.org/view.php?id=CVE-2022-22173
A Missing Release of Memory after Effective Lifetime vulnerability in the Public Key Infrastructure daemon (pkid) of Juniper Networks Junos OS allows an unauthenticated networked attacker to cause Denial of Service (DoS). In a scenario where Public Key Infrastructure (PKI) is used in combination with Certificate Revocation List (CRL), if the CRL fails to download the memory allocated to store the CRL is not released. Repeated occurrences will eventually consume all available memory and lead to an inoperable state of the affected system causing a DoS. This issue affects Juniper Networks Junos OS: All versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R2-S9, 18.4R3-S10; 19.1 versions prior to 19.1R2-S3, 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R3-S4; 19.4 versions prior to 19.4R2-S5, 19.4R3-S5; 20.1 versions prior to 20.1R3-S1; 20.2 versions prior to 20.2R3-S2; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2, 21.1R3; 21.2 versions prior to 21.2R1-S1, 21.2R2. This issue can be observed by monitoring the memory utilization of the pkid process via: root@jtac-srx1500-r2003> show system processes extensive | match pki 20931 root 20 0 733M 14352K select 0:00 0.00% pkid which increases over time: root@jtac-srx1500-r2003> show system processes extensive | match pki 22587 root 20 0 901M 181M select 0:03 0.00% pkid Una vulnerabilidad de Falta de Liberación de Memoria Después del Tiempo de Vida Efectivo en el demonio de infraestructura de clave pública (pkid) del Sistema Operativo Junos de Juniper Networks permite a un atacante no autenticado en red causar una denegación de servicio (DoS). • https://kb.juniper.net/JSA11279 • CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2022-22168
An Improper Validation of Specified Type of Input vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated adjacent attacker to trigger a Missing Release of Memory after Effective Lifetime vulnerability. Continued exploitation of this vulnerability will eventually lead to an FPC reboot and thereby a Denial of Service (DoS). This issue affects: Juniper Networks Junos OS on vMX and MX150: All versions prior to 19.2R1-S8, 19.2R3-S4; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S5, 19.4R3-S6; 20.1 versions prior to 20.1R3-S2; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2-S1, 21.1R3; 21.2 versions prior to 21.2R1-S1, 21.2R2; 21.3 versions prior to 21.3R1-S1, 21.3R2. Una vulnerabilidad de Comprobación Inapropiada del Tipo de Entrada especificado en el kernel del Sistema Operativo Junos de Juniper Networks permite a un atacante adyacente no autenticado desencadenar una vulnerabilidad de Falta de Liberación de Memoria Después del Tiempo de Vida Efectivo. Una explotación continuada de esta vulnerabilidad conllevará finalmente a un reinicio del FPC y, por tanto, una denegación de servicio (DoS). • https://kb.juniper.net/JSA11275 • CWE-401: Missing Release of Memory after Effective Lifetime CWE-1287: Improper Validation of Specified Type of Input •
