Synopsis :

The remote version of Mozilla Thunderbird is affected by an attachment
spoofing vulnerability.

Description :

The remote host is using Mozilla Thunderbird, an email client.

The remote version of this software does not display attachments
correctly in emails. Using an overly-long filename and
specially crafted Content-Type headers, an attacker may be able to
leverage this issue to spoof the file extension and associated file
type icon and trick a user into executing an arbitrary program.
