Microsoft Exchange Server TNEF decoding code execution
| exchange-tnef-code-execution (47670) |  High Risk |
Description:
Microsoft Exchange Server could allow a remote attacker to execute arbitrary code on the system, caused by improper decoding of Transport Neutral Encapsulation Format (TNEF) message data. By sending a specially-crafted TNEF message to a vulnerable Exchange Server, a remote attacker could exploit this vulnerability to corrupt memory and execute arbitrary code on the system, once the Exchange Server Information Store processes the message or a victim opens the message.
