** Changed in: linux-lts-quantal (Ubuntu Precise)
       Status: New => Fix Committed

** Changed in: linux (Ubuntu Utopic)
       Status: New => Fix Committed

** Changed in: linux-lts-raring (Ubuntu Precise)
       Status: New => Fix Committed

** Description changed:

- The internal function inode_capable 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 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.
