DESCRIPTION

* CVE-2016-0774: Information leak in the pipe system call on failed atomic read.

The fix for CVE-2015-1805 incorrectly kept buffer offset and length in sync
on a failed atomic read, leading to piper buffer state corruption.  A
local, unprivileged user could use this flaw to cause a denial-of-service
or leak kernel memory to userspace.
