util-linux is a suite of Linux programs including mount and umount,
|
|
programs used to mount and unmount filesystems.

|
|
Ludwig Nussel discovered that the check_special_mountprog() and
|
|
check_special_umountprog() functions call setuid() and setgid() in the
|
|
wrong order and do not check the return values, which can lead to
|
|
privileges being dropped improperly.
|
|

|
|
<impact type="high">
|
|
<p>
|
|
A local attacker may be able to exploit this vulnerability by using
|
|
mount helpers such as the mount.nfs program to gain root privileges and
|
|
run arbitrary commands.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</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-2.12r-r8"</code>
