<access>remote</access>
<affected>
<package name="net-fs/cifs-utils" auto="yes" arch="*">
<unaffected range="ge">6.11</unaffected>
<vulnerable range="lt">6.11</vulnerable>
</package>
</affected>
<background>
<p>The LinuxCIFS utils are a collection of tools for managing Linux CIFS
Client Filesystems.
</p>
</background>
<description>
<p>The mount.cifs utility had a shell injection issue where one can embed
shell commands via the username mount option. Those commands will be run
via popen() in the context of the user calling mount.
</p>
</description>
<impact type="normal">
<p>A remote attacker could entice a user to use a specially crafted
argument using mount.cifs, possibly resulting in execution of arbitrary
code with the privileges of the process or a Denial of Service condition.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All LinuxCIFS users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/cifs-utils-6.11"
</code>
</resolution>
