      Bugs: #69181
        ID: 200411-06

Synopsis
=======
MIME-tools doesn't handle empty MIME boundaries correctly. This may
prevent some virus-scanning programs which use MIME-tools from
detecting certain viruses.

Background
=========
MIME-tools is a Perl module containing functions to handle MIME
attachments.

Affected packages
================
    -------------------------------------------------------------------
     Package              /  Vulnerable  /                  Unaffected
    -------------------------------------------------------------------
  1  dev-perl/MIME-tools       < 5.415                        >= 5.415

Description
==========
MIME-tools doesn't correctly parse attachment boundaries with an empty
name (boundary="").

Impact
=====
An attacker could send a carefully crafted email and evade detection on
some email virus-scanning programs using MIME-tools for attachment
decoding.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All MIME-tools users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-perl/MIME-tools-5.415"
