<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).

<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
|
|
">=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.
