Microsoft Exchange Server and Outlook TNEF overflow
| win-tnef-overflow (22878) |  High Risk |
Description:
Microsoft Office, Microsoft Outlook, and Microsoft Exchange Server are vulnerable to an integer overflow in the handling of Transport Neutral Encapsulation Format (TNEF) MIME attachments, which could allow a remote attacker to execute arbitrary code. The TNEF protocol, used to package and send messages formatted as Rich Text Format (FTF), is used by Microsoft Outlook and Exchange Server. By sending a specially-crafted email message that uses the TNEF protocol, a remote attacker could overflow a buffer and execute arbitrary code to gain complete control over the affected system, once the malicious message is opened or previewed in Outlook or processed by the Microsoft Exchange Server Information Store.
Platforms Affected:
- Microsoft, Exchange Server 2000 SP3
- Microsoft, Exchange Server 5.0 SP2
- Microsoft, Exchange Server 5.5 SP4
- Microsoft, Office 2000 SP3
- Microsoft, Office 2003 SP1
- Microsoft, Office 2003 SP2
- Microsoft, Office XP SP3
