+ <title>util-linux: User-assisted execution of arbitrary code</title>
+ <synopsis>A vulnerability was discovered in util-linux, which could
+ potentially lead to the execution of arbitrary code.

+ <affected>
+ <package name="sys-apps/util-linux" auto="yes" arch="*">

+ </package>
+ </affected>
+ <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 "&gt;=sys-apps/util-linux-2.30.2-r1"
+ </code>
