Description Vincent Danen 2010-08-03 22:13:34 UTC

A flaw was found in the way that the Mantis BTS handled attachments and MIME types.  A user could upload an HTML file renamed to a .gif and Mantis would calculate the actual MIME type of the file as text/html.  A user tricked into thinking they were clicking a .gif attachment would instead have the full HTML file rendered in the browser, rather than having it treated as a downloadable file or displayed in plain text.

This was corrected in upstream version 1.2.2 and affects current Fedora 12, 13, rawhide, and EPEL5.

Created mantis tracking bugs for this issue

Affects: fedora-all [bug 620993]

Comment 2 Gianluca Sforna 2010-08-04 07:26:57 UTC

Hi Vincent, thanks for the report. It seems to me the flaw reported here affects 1.2.x versions. The version we are still shipping in all Fedora/EPEL branches (1.1.8) is not affected by the flaw.

Comment 3 Vincent Danen 2010-08-04 15:20:13 UTC

Ah yes, you're absolutely correct.  I missed the part in the blog post indicating it was 1.2.x.  Thanks for looking, I'll close this and the tracker then.
