<background>
<p>Kpathsea is a library to do path searching. It is used by TeX Live and
others TeX related software.
</p>
</background>
<description>
<p>It was discovered that the mpost program from the shell_escape_commands
list is capable of executing arbitrary external programs during the
conversion of .tex files. The responsible function is runpopen()
(texmfmp.c).
</p>
</description>
<impact type="normal">
<p>A remote attacker, by enticing a user to open a specially crafted .tex
file, could possibly execute arbitrary code with the privileges of the
process.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All Kpathsea users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose
"&gt;=dev-libs/kpathsea-6.2.2_p20160523"
</code>
<p>Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these packages.
