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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
