CVE-2018-15497

Estado: ModificadaCrítica (9.8)—

The Mitel MiVoice 5330e VoIP device is affected by memory corruption flaws in the SIP/SDP packet handling functionality. An attacker can exploit this issue remotely, by sending a particular pattern of SIP/SDP packets, to cause a denial of service state in the affected devices and probably remote code execution.
