"value": "A Use-After-Free vulnerability in the\u00a0Layer 2 Address Learning Daemon (l2ald)\n\n of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause l2ald to crash leading to a Denial-of-Service (DoS).\n\nIn an EVPN-VXLAN scenario,\u00a0when \n\nstate updates are received and processed by the affected system, the correct order of some processing steps is not ensured, which can lead to an l2ald crash and restart. Whether the crash occurs depends on system internal timing which is outside the attackers control.\nThis issue affects:\n\nJunos OS:\u00a0\n\n\n\n * All versions before 20.4R3-S8,\n * 21.2 versions before 21.2R3-S6,\n * 21.3 versions before 21.3R3-S5,\n * 21.4 versions before 21.4R3-S4,\n * 22.1 versions before 22.1R3-S3,\n * 22.2 versions before 22.2R3-S1,\n * 22.3 versions before 22.3R3,,\n * 22.4 versions before 22.4R2;\n\n\n\n\nJunos OS Evolved:\u00a0\n\n\n\n * All versions before 20.4R3-S8-EVO,\n * 21.2-EVO versions before 21.2R3-S6-EVO,\u00a0\n * 21.3-EVO\n\n versions before 21.3R3-S5-EVO,\n * 21.4-EVO\n\n versions before 21.4R3-S4-EVO,\n * 22.1-EVO\n\n versions before 22.1R3-S3-EVO,\n * 22.2-EVO\n\n versions before 22.2R3-S1-EVO,\n * 22.3-EVO\n\n versions before 22.3R3-EVO,\n * 22.4-EVO\n\n versions before 22.4R2-EVO."

"value": "Una vulnerabilidad de Use-After-Free en el daemon de aprendizaje de direcciones de capa 2 (l2ald) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque que l2ald falle, lo que provoca una denegaci\u00f3n de servicio (DoS). En un escenario EVPN-VXLAN, cuando el sistema afectado recibe y procesa actualizaciones de estado, no se garantiza el orden correcto de algunos pasos de procesamiento, lo que puede provocar un bloqueo y reinicio de l2ald. Que se produzca el fallo depende de la sincronizaci\u00f3n interna del sistema, que est\u00e1 fuera del control de los atacantes. Este problema afecta a: Junos OS: * Todas las versiones anteriores a 20.4R3-S8, * Versiones 21.2 anteriores a 21.2R3-S6, * Versiones 21.3 anteriores a 21.3R3-S5, * Versiones 21.4 anteriores a 21.4R3-S4, * Versiones 22.1 anteriores a 22.1R3- S3, * 22.2 versiones anteriores a 22.2R3-S1, * 22.3 versiones anteriores a 22.3R3, * 22.4 versiones anteriores a 22.4R2; Junos OS Evolved: * Todas las versiones anteriores a 20.4R3-S8-EVO, * Versiones 21.2-EVO anteriores a 21.2R3-S6-EVO, * Versiones 21.3-EVO anteriores a 21.3R3-S5-EVO, * Versiones 21.4-EVO anteriores a 21.4R3- S4-EVO, *versiones 22.1-EVO anteriores a 22.1R3-S3-EVO, *versiones 22.2-EVO anteriores a 22.2R3-S1-EVO, *versiones 22.3-EVO anteriores a 22.3R3-EVO, *versiones 22.4-EVO anteriores a 22.4R2- EVO."
