  <title>MIME-tools: Virus detection evasion</title>
  <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.

    <package name="dev-perl/MIME-tools" auto="yes" arch="*">

  <background>
    <p>
    MIME-tools is a Perl module containing functions to handle MIME
    attachments.
    </p>
  </background>
  <description>
    <p>
    MIME-tools doesn't correctly parse attachment boundaries with an empty
    name (boundary="").
    </p>
  </description>
  <impact type="low">
    <p>
    An attacker could send a carefully crafted email and evade detection on
    some email virus-scanning programs using MIME-tools for attachment
    decoding.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All MIME-tools users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-perl/MIME-tools-5.415&quot;</code>
  </resolution>
