Which of the following BEST describe this type of attack?

A university with remote campuses, which all use different service providers, loses Internet connectivity across all locations. After a few minutes, Internet and VoIP services are restored, only to go offline again at random intervals, typically within four minutes of services being restored. Outages continue throughout the day, impacting all inbound and outbound connections and services. Services that are limited to the local LAN or WiFi network are not impacted, but all WAN and VoIP services are affected.

Later that day, the edge-router manufacturer releases a CVE outlining the ability of an attacker to exploit the SIP protocol handling on devices, leading to resource exhaustion and system reloads.

Answer: A,C

Explanation:

"According to its self-reported version, the Cisco IOS software running on the remote device is affected by a denial of service vulnerability in the Session Initiation Protocol (SIP) gateway implementation due to improper handling of malformed SIP messages. An unauthenticated, remote attacker can exploit this, via crafted SIP messages, to cause memory leakage, resulting in an eventual reload of the affected device."
