  <description>
    <p>
    acroread contains two errors in the handling of UUEncoded filenames.
    First, it fails to check the length of a filename before copying it
    into a fixed size buffer and, secondly, it fails to check for the
    backtick shell metacharacter in the filename before executing a command
    with a shell.
    </p>
  </description>
  <impact type="normal">
    <p>
    By enticing a user to open a PDF with a specially crafted filename, an
    attacker could execute arbitrary code or programs with the permissions
    of the user running acroread.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time. All users are encouraged to
    upgrade to the latest available version of acroread.
    </p>
  </workaround>
  <resolution>
    <p>
    All acroread users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=app-text/acroread-5.09"
    # emerge "&gt;=app-text/acroread-5.09"</code>
  </resolution>
