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"
