ELF objects.

<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 ">=dev-libs/elfutils-0.159"
</code>
</resolution>
