CVE-2014-4014

[John Johansen]

The capabilities implementation in the Linux kernel before 3.14.8 does not properly consider that namespaces are inapplicable to inodes, which allows local users to bypass intended chmod restrictions by first creating a user namespace, as demonstrated by setting the setgid bit on a file with group ownership of root.

Break-Fix: 1a48e2ac034d47ed843081c4523b63c46b46888b 23adbe12ef7d3d4195e80800ab36b37bee28cd03
