Descriptions
An Improper Validation of Syntactic Correctness of Input vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS).
If a BGP update is received over an established BGP session which contains a tunnel encapsulation attribute with a specifically malformed TLV, rpd will crash and restart.
This issue affects Juniper Networks
Junos OS:
* 20.4 versions 20.4R1 and later 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-S5;
* 22.1 versions earlier than 22.1R3-S4;
* 22.2 versions earlier than 22.2R3-S3;

* 22.4 versions earlier than 22.4R3;
* 23.2 versions earlier than 23.2R1-S2, 23.2R2;
Junos OS Evolved:
* 20.4-EVO versions 20.4R1-EVO and later versions earlier than 20.4R3-S9-EVO;
* 21.2-EVO versions earlier than 21.2R3-S7-EVO;
* 21.3-EVO versions earlier than 21.3R3-S5-EVO;

* 22.3-EVO versions earlier than 22.3R3-S1-EVO;
* 22.4-EVO versions earlier than 22.4R3-EVO;
* 23.2-EVO versions earlier than 23.2R1-S2-EVO, 23.2R2-EVO;
This issue does not affect Juniper Networks
* Junos OS versions earlier than 20.4R1;
* Junos OS Evolved versions earlier than 20.4R1-EVO.
This is a related but separate issue than the one described in JSA79095.
Una validación inadecuada de la vulnerabilidad de corrección sintáctica de entrada en el daemon de protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante no autenticado basado en red provoque una denegación de servicio (DoS). Si se recibe una actualización de BGP a través de una sesión BGP establecida que contiene un atributo de encapsulación de túnel con un TLV específicamente mal formado, rpd fallará y se reiniciará. Este problema afecta a Juniper Networks Junos OS: * 20.4 versiones 20.4R1 y versiones posteriores anteriores a 20.4R3-S9; * Versiones 21.2 anteriores a 21.2R3-S7; * Versiones 21.3 anteriores a 21.3R3-S5; * Versiones 21.4 anteriores a 21.4R3-S5; * Versiones 22.1 anteriores a 22.1R3-S4; * Versiones 22.2 anteriores a 22.2R3-S3; * Versiones 22.3 anteriores a 22.3R3-S1; * Versiones 22.4 anteriores a 22.4R3; * Versiones 23.2 anteriores a 23.2R1-S2, 23.2R2; Junos OS Evolved: * 20.4-EVO versiones 20.4R1-EVO y versiones posteriores anteriores a 20.4R3-S9-EVO; * Versiones 21.2-EVO anteriores a 21.2R3-S7-EVO; * Versiones 21.3-EVO anteriores a 21.3R3-S5-EVO; * Versiones 21.4-EVO anteriores a 21.4R3-S5-EVO; * Versiones 22.1-EVO anteriores a 22.1R3-S4-EVO; * Versiones 22.2-EVO anteriores a 22.2R3-S3-EVO; * Versiones 22.3-EVO anteriores a 22.3R3-S1-EVO; * Versiones 22.4-EVO anteriores a 22.4R3-EVO; * Versiones 23.2-EVO anteriores a 23.2R1-S2-EVO, 23.2R2-EVO; Este problema no afecta a Juniper Networks * versiones de Junos OS anteriores a 20.4R1; * Versiones de Junos OS Evolved anteriores a 20.4R1-EVO. Este es un problema relacionado pero independiente del descrito en JSA79095.
