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"
