<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.

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.

<description>
|
|
<p>
|
|
dispatch-conf and qpkg use predictable filenames for temporary files.

|
<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.

<workaround>

<p>
|
|
There is no known workaround at this time.

All Portage users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-apps/portage-2.0.51-r3"</code>

All Gentoolkit users should upgrade to the latest version:
|

</p>
|

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-portage/gentoolkit-0.2.0_pre8-r1"</code>
