Mozilla Thunderbird < 1.5 Attachment Extension Spoofing

Medium Nessus Plugin ID 20735


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


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.


Upgrade to Mozilla Thunderbird 1.5 or later.
