DESCRIPTION

* Improve fix for Permission bypass when checking credentials for fs accesses.

An incorrect backport of the fix can result in a kernel error when
attempting to access another processes pagemep in proc.


* CVE-2016-1583: Privilege escalation in eCryptfs.

eCryptfs was incorrectly trying to use the mmap() file operation on lower
filesystem that may not support it.  A local, unprivileged user could use
this flaw to cause a denial-of-service through recursive faults or
potentially escalate privileges.
