| Revision Date: | 2014-08-18 | Version: | 1 | | Title: | CVE-2014-5206 on Ubuntu 12.04 LTS (precise) - high. | | Description: | The do_remount function in fs/namespace.c in the Linux kernel through 3.16.1 does not maintain the MNT_LOCK_READONLY bit across a remount of a bind mount, which allows local users to bypass an intended read-only restriction and defeat certain sandbox protection mechanisms via a "mount -o remount" command within a user namespace. Kenton Varda discovered a flaw with read-only bind mounds when used with user namespaces. An unprivileged local user could exploit this flaw to gain full write privileges to a mount that should be read only.
