This kernel live patch for Linux Kernel 3.12.51-60.20.2 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)
