CVE-2014-5207: Improper Privilege Management

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, ...

Ubuntu 12.04 LTS : linux-lts-trusty vulnerabilities (USN-2317-1)

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...

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-2014-4014

The CVE-2014-4014 issue is a Linux kernel local privilege escalation affecting versions before 3.14.8. The root cause is that namespaces are inapplicable to inodes, allowing a local user who creates a user namespace to bypass chmod restrictions by setting the setgid bit on a file with root group ...

[oss-security] CVE-2014-4014: Linux kernel user namespace bug

The internal function inodecapable was used inappropriately. Depending on configuration, this may be usable to escalate privileges. A cursory inspection of my Fedora box suggests that it is not vulnerable to the obvious way to exploit this bug. The fix should appear in Linus' -master shortly, and...
