<announced>October 28, 2013</announced>
<revised>October 28, 2013: 2</revised>
<bug>367891</bug>
<access>local</access>
<affected>
<package name="sys-devel/pmake" auto="yes" arch="*">
<unaffected range="ge">1.111.3.1</unaffected>
<vulnerable range="lt">1.111.3.1</vulnerable>
</package>

<background>
<p>pmake is Debian’s version of NetBSD’s make, a tool to build programs
in parallel.
</p>
</background>
<description>
<p>/usr/share/mk/bsd.lib.mk and /usr/share/mk/bsd.prog.mk create temporary
files insecurely, with predictable names (/tmp/_depend[PID]), and
without using $TMPDIR.
</p>
</description>
<impact type="low">
<p>The make include files allow local users to overwrite arbitrary files
via a symlink attack.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All pmake users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-devel/pmake-1.111.3.1"
</code>
</resolution>
