An update that solves three vulnerabilities can now be installed.

Description:

This kernel live patch for Linux Kernel 3.12.49-11.1 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)
