<background>
|
|
<p>util-linux is a suite of Linux programs including mount and umount,
|
|
programs used to mount and unmount filesystems.
|
|
</p>
|
|
</background>
|
|
<description>
|
|
<p>It was discovered that the umount bash-completion as provided by
|
|
util-linux does not escap mount point paths.
|
|
</p>
|
|
</description>
|
|
<impact type="high">
|
|
<p>An attacker controlling a volume label could entice a user with
|
|
privileges to mount/umount filesystems to use umount command with auto
|
|
completion, possibly resulting in execution of arbitrary code with root
|
|
privileges.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>Disable Bash-completion or remove
|
|
“/usr/share/bash-completion/completions/umount”.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All util-linux users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-apps/util-linux-2.30.2-r1"
|
|
</code>
