Advisory:
Updated kernel-linus provides upstream 3.12.18 kernel and fixes the following
security issues:

Buffer overflow in the complete_emulated_mmio function in arch/x86/kvm/
x86.c in the Linux kernel before 3.13.6 allows guest OS users to execute
arbitrary code on the host OS by leveraging a loop that triggers an
invalid memory copy affecting certain cancel_work_item data. 
(CVE-2014-0049)

The get_rx_bufs function in drivers/vhost/net.c in the vhost-net subsystem
in the Linux kernel package before 2.6.32-431.11.2 on Red Hat Enterprise
Linux (RHEL) 6 does not properly handle vhost_get_vq_desc errors, which
allows guest OS users to cause a denial of service (host OS crash) via
unspecified vectors. (CVE-2014-0055)

The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through
3.13.5 does not properly handle uncached write operations that copy fewer
than the requested number of bytes, which allows local users to obtain
sensitive information from kernel memory, cause a denial of service
(memory corruption and system crash), or possibly gain privileges via a
writev system call with a crafted pointer. (CVE-2014-0069)

drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable
buffers are disabled, does not properly validate packet lengths, which
allows guest OS users to cause a denial of service (memory corruption and
host OS crash) or possibly gain privileges on the host OS via crafted
packets, related to the handle_rx and get_rx_bufs functions. 
(CVE-2014-0077)

Oter fixes in this update:
- switch hugepages back to madvise to fix performance regression (mga#12994)
- enable Intel P-state driver (mga#13080)
- fix r8169 suspend/resume issue (mga#13255)

All ok 32bit, working dkms modules all build ok.

It'll need testing 64bit before we can validate, if anyone can do so please..

Whiteboard: (none) => mga4-32-ok

Testing complete mga4 64.

Whiteboard: mga4-32-ok => mga4-32-ok mga6-64-ok

Validating. Advisory uploaded.

There is no mention of CVE-2014-2851 in the advisory for this one. It might need adding.
