Description:
A vulnerability has been reported in util-linux, which potentially can be exploited by malicious, local users to perform certain actions with escalated privileges.
The vulnerability is caused due to the mount and umount programs incorrectly checking the return values of the "setuid()" and "setgid()" functions when dropping privileges. This can potentially be exploited to perform certain actions with escalated privileges via e.g. the mount.nfs utility.
The vulnerability is reported in version 2.12r. Other versions may also be affected.
Solution:
Fixed in the util-linux-ng repository.
