CVE-2014-5206

CVE-2014-5206 : In Linux kernel versions up to 3.16.1, the do_remount function in fs/namespace.c fails to preserve the MNT_LOCK_READONLY flag across remounts of bind mounts. This allows a local user to bypass the intended read-only restriction by using a mount -o remount within a user namespace, ...

CVE-2014-5206

The doremount function in fs/namespace.c in the Linux kernel through 3.16.1 does not maintain the MNTLOCKREADONLY 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"...

CVE-2014-5207

fs/namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNTNODEV, MNTNOSUID, and MNTNOEXEC and changing MNTATIMEMASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, ...

USN-2317-1: Linux kernel (Trusty HWE) vulnerabilities

Eric W. Biederman discovered a flaw with the mediation of mount flags in the Linux kernel's user namespace subsystem. An unprivileged user could exploit this flaw to by-pass mount restrictions, and potentially gain administrative privileges. CVE-2014-5207 Kenton Varda discovered a flaw with...
