An attacker could exploit this vulnerability by sending crafted HTTP packets through an established connection to be parsed by Snort 3. A successful exploit could allow the attacker to cause a DoS condition when the Snort 3 Detection Engine unexpectedly restarts."},{"lang":"es","value":"Múltiples productos Cisco se ven afectados por una vulnerabilidad en el motor de detección de Snort 3 que podría permitir a un atacante remoto no autenticado provocar el reinicio del motor de detección de Snort 3, lo que resultaría en una interrupción de la inspección de paquetes.\n\nEsta vulnerabilidad se debe a una comprobación de errores incompleta al analizar los campos de Multicast DNS del encabezado HTTP.
