Описание
Уязвимость реализации протокола Server Message Block Version 2 (SMB2) системы обнаружения вторжений Snort микропрограммного обеспечения межсетевых экранов Cisco Firepower Threat Defense (FTD), микропрограммного обеспечения cетевых устройств Cisco Meraki MX, средства контроля безопасности промышленных сетей Cisco Cyber Vision и облачного сервиса безопасности Cisco Umbrella связана с неправильной очисткой динамической памяти. Эксплуатация уязвимости позволяет нарушителю, действующему удаленно, обойти ограничения безопасности и вызвать отказ в обслуживании путем отправки специально сформированных SMB2 пакетов

Multiple vulnerabilities in the Server Message Block Version 2 (SMB2) processor of the Snort detection engine on multiple Cisco products could allow an unauthenticated, remote attacker to bypass the configured policies or cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to improper management of system resources when the Snort detection engine is processing SMB2 traffic. An attacker could exploit these vulnerabilities by sending a high rate of certain types of SMB2 packets through an affected device. A successful exploit could allow the attacker to trigger a reload of the Snort process, resulting in a DoS condition. Note: When the snort preserve-connection option is enabled for the Snort detection engine, a successful exploit could also allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network. The snort preserve-connection setting is enabled by default. See the Details ["#details"]
