<title>Portage, Gentoolkit: Temporary file vulnerabilities</title>
<synopsis>
dispatch-conf (included in Portage) and qpkg (included in Gentoolkit) are
vulnerable to symlink attacks, potentially allowing a local user to
overwrite arbitrary files with the rights of the user running the script.

<p>
Portage is Gentoo's package management tool. The dispatch-conf utility
allows for easy rollback of configuration file changes and automatic
updates of configurations files never modified by users. Gentoolkit is
a collection of Gentoo specific administration scripts, one of which is
the portage querying tool qpkg.
</p>

<description>
<p>
dispatch-conf and qpkg use predictable filenames for temporary files.
</p>
</description>
<impact type="normal">
<p>
A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When
an affected script is called, this would result in the file to be
overwritten with the rights of the user running the dispatch-conf or
qpkg, which could be the root user.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Portage users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=sys-apps/portage-2.0.51-r3&quot;</code>
<p>
All Gentoolkit users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-portage/gentoolkit-0.2.0_pre8-r1&quot;</code>
