  <background>
    <p>Elfutils provides a library and utilities to access, modify and analyse
      ELF objects.
    </p>
  </background>
  <description>
    <p>An integer overflow, in the check_section function of dwarf_begin_elf.c,
      in the libdw library can lead to a heap-based buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted file,
      possibly resulting in the execution of arbitrary code with the privileges
      of the process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All elfutils users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-libs/elfutils-0.159"
    </code>
