  <description>
This kernel live patch for Linux Kernel 3.12.51-60.25.1 fixes three security
issues:

Fixes:
- CVE-2016-0728: A reference leak in keyring handling with
  join_session_keyring() could lead to local attackers gain root
  privileges. (bsc#962078).
- CVE-2015-8660: The ovl_setattr function in fs/overlayfs/inode.c in the
  Linux kernel through 4.3.3 attempts to merge distinct setattr
  operations, which allows local users to bypass intended access
  restrictions and modify the attributes of arbitrary overlay files via
  a crafted application. (bsc#960329)
- CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in
  the Linux kernel allowed local users to bypass intended AF_UNIX socket
  permissions or cause a denial of service (panic) via crafted epoll_ctl
  calls. (bsc#955837)
