An Improper Check for Unusual or Exceptional Conditions vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause rpd to crash, leading to Denial of Service (DoS). On all Junos OS and Junos OS Evolved platforms, when NETCONF and gRPC are enabled, and a specific query is executed via Dynamic Rendering (DREND), rpd will crash and restart. Continuous execution of this specific query will cause a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS * 22.2 versions earlier than 22.2R2-S2, 22.2R3; * 22.3 versions earlier than 22.3R2, 22.3R3. Juniper Networks Junos OS Evolved * 22.2 versions earlier than 22.2R2-S2-EVO, 22.2R3-EVO; * 22.3 versions earlier than 22.3R2-EVO, 22.3R3-EVO. This issue does not affect Juniper Networks: Junos OS versions earlier than 22.2R1; Junos OS Evolved versions earlier than 22.2R1-EVO. Una vulnerabilidad de verificación inadecuada de condiciones inusuales o excepcionales en Routing Protocol Daemon (RPD) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante no autenticado basado en la red cause que rpd falle, lo que lleva a una denegación de servicio (DoS). En todas las plataformas Junos OS y Junos OS Evolved, cuando NETCONF y gRPC están habilitados y se ejecuta una consulta específica mediante representación dinámica (DREND), rpd fallará y se reiniciará. La ejecución continua de esta consulta específica provocará una condición sostenida de Denegación de Servicio (DoS). • https://supportportal.juniper.net/JSA75755 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N • CWE-754: Improper Check for Unusual or Exceptional Conditions •

A Missing Release of Memory after Effective Lifetime vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause an rpd crash, leading to Denial of Service (DoS). On all Junos OS and Junos OS Evolved platforms, when traffic engineering is enabled for OSPF or ISIS, and a link flaps, a patroot memory leak is observed. This memory leak, over time, will lead to an rpd crash and restart. The memory usage can be monitored using the below command. user@host> show task memory detail | match patroot This issue affects: Juniper Networks Junos OS * All versions earlier than 21.2R3-S3; * 21.3 versions earlier than 21.3R3-S5; * 21.4 versions earlier than 21.4R3-S3; * 22.1 versions earlier than 22.1R3; * 22.2 versions earlier than 22.2R3. Juniper Networks Junos OS Evolved * All versions earlier than 21.3R3-S5-EVO; * 21.4 versions earlier than 21.4R3-EVO; * 22.1 versions earlier than 22.1R3-EVO; * 22.2 versions earlier than 22.2R3-EVO. Una vulnerabilidad de liberación de memoria faltante después de la vida útil efectiva en Routing Protocol Daemon (RPD) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque un bloqueo de rpd, lo que lleva a una denegación de servicio (DoS). En todas las plataformas Junos OS y Junos OS Evolved, cuando la ingeniería de tráfico está habilitada para OSPF o ISIS y un enlace falla, se observa una pérdida de memoria de patroot. Esta pérdida de memoria, con el tiempo, provocará un bloqueo y reinicio del rpd. • https://supportportal.juniper.net/JSA75754 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N • CWE-401: Missing Release of Memory after Effective Lifetime •

A Missing Release of Memory after Effective Lifetime vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). In a Juniper Flow Monitoring (jflow) scenario route churn that causes BGP next hops to be updated will cause a slow memory leak and eventually a crash and restart of rpd. Thread level memory utilization for the areas where the leak occurs can be checked using the below command: user@host> show task memory detail | match so_in so_in6 28 32 344450 11022400 344760 11032320 so_in 8 16 1841629 29466064 1841734 29467744 This issue affects: Junos OS * 21.4 versions earlier than 21.4R3; * 22.1 versions earlier than 22.1R3; * 22.2 versions earlier than 22.2R3. Junos OS Evolved * 21.4-EVO versions earlier than 21.4R3-EVO; * 22.1-EVO versions earlier than 22.1R3-EVO; * 22.2-EVO versions earlier than 22.2R3-EVO. This issue does not affect: Juniper Networks Junos OS versions earlier than 21.4R1. Juniper Networks Junos OS Evolved versions earlier than 21.4R1. Una vulnerabilidad de liberación de memoria faltante después de la vida útil efectiva en Routing Protocol Daemon (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS). En un escenario de Juniper Flow Monitoring (jflow), la rotación de rutas que hace que los siguientes saltos de BGP se actualicen provocará una pérdida de memoria lenta y, finalmente, un bloqueo y reinicio de rpd. La utilización de la memoria a nivel de subproceso para las áreas donde se produce la fuga se puede verificar usando el siguiente comando: user@host> show task memory detail | match so_in so_in6 28 32 344450 11022400 344760 11032320 so_in 8 16 1841629 29466064 1841734 29467744. Este problema afecta a: Junos OS * 21.4 versiones anteriores a 21.4R3; * Versiones 22.1 anteriores a 22.1R3; * Versiones 22.2 anteriores a 22.2R3. • https://supportportal.juniper.net/JSA75752 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L • CWE-401: Missing Release of Memory after Effective Lifetime •

An Unsupported Feature in the UI vulnerability in Juniper Networks Junos OS on MX Series and EX9200 Series allows an unauthenticated, network-based attacker to cause partial impact to the integrity of the device. If the "tcp-reset" option is added to the "reject" action in an IPv6 filter which matches on "payload-protocol", packets are permitted instead of rejected. This happens because the payload-protocol match criteria is not supported in the kernel filter causing it to accept all packets without taking any other action. As a fix the payload-protocol match will be treated the same as a "next-header" match to avoid this filter bypass. This issue doesn't affect IPv4 firewall filters. This issue affects Juniper Networks Junos OS on MX Series and EX9200 Series: * All versions earlier than 20.4R3-S7; * 21.1 versions earlier than 21.1R3-S5; * 21.2 versions earlier than 21.2R3-S5; * 21.3 versions earlier than 21.3R3-S4; * 21.4 versions earlier than 21.4R3-S4; * 22.1 versions earlier than 22.1R3-S2; * 22.2 versions earlier than 22.2R3-S2; * 22.3 versions earlier than 22.3R2-S2, 22.3R3; * 22.4 versions earlier than 22.4R1-S2, 22.4R2-S2, 22.4R3. Una característica no compatible en la vulnerabilidad de la interfaz de usuario en Juniper Networks Junos OS en las series MX y EX9200 permite que un atacante no autenticado basado en la red cause un impacto parcial en la integridad del dispositivo. Si se agrega la opción "tcp-reset" a la acción "reject" en un filtro IPv6 que coincide con el "payload-protocol", los paquetes se permiten en lugar de rechazarse. • https://supportportal.juniper.net/JSA75748 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N • CWE-447: Unimplemented or Unsupported Feature in UI •

A Double Free vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). In a remote access VPN scenario, if a "tcp-encap-profile" is configured and a sequence of specific packets is received, a flowd crash and restart will be observed.
