CVE-2024-39538

A Buffer Copy without Checking Size of Input vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved on ACX7000 Series allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).When multicast traffic with a specific, valid (S,G) is received, evo-pfemand crashes which leads to an outage of the affected FPC until it is manually recovered. This issue affects Junos OS Evolved on ACX7000 Series: * All versions before 21.2R3-S8-EVO, * 21.4-EVO versions before 21.4R3-S7-EVO, * 22.2-EVO versions before 22.2R3-S4-EVO, * 22.3-EVO versions before 22.3R3-S3-EVO, * 22.4-EVO versions before 22.4R3-S2-EVO, * 23.2-EVO versions before 23.2R2-EVO, * 23.4-EVO versions before 23.4R1-S2-EVO, 23.4R2-EVO.

Summary		(es) Una vulnerabilidad de copia de búfer sin verificar el tamaño de entrada en el daemon de administración PFE (evo-pfemand) de Juniper Networks Junos OS Evolved en la serie ACX7000 permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). Cuando el tráfico de multidifusión con Se recibe un (S,G) específico y válido, evo-pfemand se bloquea, lo que provoca una interrupción del FPC afectado hasta que se recupera manualmente. Este problema afecta a Junos OS Evolved en la serie ACX7000: * Todas las versiones anteriores a 21.2R3-S8-EVO, * Versiones 21.4-EVO anteriores a 21.4R3-S7-EVO, * Versiones 22.2-EVO anteriores a 22.2R3-S4-EVO, * 22.3- Versiones EVO anteriores a 22.3R3-S3-EVO, * Versiones 22.4-EVO anteriores a 22.4R3-S2-EVO, * Versiones 23.2-EVO anteriores a 23.2R2-EVO, * Versiones 23.4-EVO anteriores a 23.4R1-S2-EVO, 23.4R2- EVO.
