<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>
