    <package name="app-editors/hteditor" auto="yes" arch="*">

    HT is a hex editor, designed to help analyse and modify executable
    files.

  <description>
    <p>
    Tavis Ormandy of the Gentoo Linux Security Team discovered an integer
    overflow in the ELF parser, leading to a heap-based buffer overflow.
    The vendor has reported that an unrelated buffer overflow has been
    discovered in the PE parser.
    </p>
  </description>
  <impact type="normal">
    <p>
    Successful exploitation would require the victim to open a specially
    crafted file using HT, potentially permitting an attacker to execute
    arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All hteditor users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-editors/hteditor-0.8.0-r2&quot;</code>
  </resolution>
