3.8.13.14 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Prarit Bhargava <pra...@redhat.com>
commit 411cabf79e684171669ad29a0628c400b4431e95 upstream.
Commit e82b89a6f19bae73fb064d1b3dd91fcefbb478f4 used strcat instead of
strcpy which can result in an overflow of newlines on the buffer.
