699047 - Replaying to Message with Attachments Can Generate Banned (executable) File Names

Status: UNCONFIRMED

(MailNews Core :: Attachments, defect)

Description

[George Sexton]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1
Build ID: 20110928134238

Steps to reproduce:

We replied to a message that had a signature image in it. Here's the header for the attachment image:

Content-Transfer-Encoding: base64
Content-ID: <sigimg1@17de55703a2cc1576a51cfa6681ad632>
Content-Type: image/gif;
 name="sigimg1"; 
Content-Disposition: inline;
 filename="sigimg1"; 



Actual results:

The reply re-generated a header for the image:

--=_0c1a775dee57102c217e67350a62b1bc
Content-Transfer-Encoding: base64
Content-ID: <[e-mail]>
Content-Type: image/gif;
 name="[e-mail]"; 
Content-Disposition: inline;
 filename="[e-mail]"; 

The problem here is that .com is a file extension for an MS-DOS executable. When the person replied to us, our mail server kicked back the message because the file extension is banned (.com).



Expected results:


The original file name should have been retained, or a file name that won't be mistaken for an executable should be used.
