Debian Bug : 766195

Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service:

CVE-2014-3610

Lars Bull of Google and Nadav Amit reported a flaw in how KVM
handles noncanonical writes to certain MSR registers. A privileged
guest user can exploit this flaw to cause a denial of service
(kernel panic) on the host.

CVE-2014-3611

Lars Bull of Google reported a race condition in in the PIT
emulation code in KVM. A local guest user with access to PIT i/o
ports could exploit this flaw to cause a denial of service (crash)
on the host.

CVE-2014-3645 / CVE-2014-3646

The Advanced Threat Research team at Intel Security discovered
that the KVM subsystem did not handle the VM exits gracefully
for the invept (Invalidate Translations Derived from EPT) and
invvpid (Invalidate Translations Based on VPID) instructions. On
hosts with an Intel processor and invept/invppid VM exit
support, an unprivileged guest user could use these instructions
to crash the guest.

CVE-2014-3647

Nadav Amit reported that KVM mishandles noncanonical addresses when
emulating instructions that change rip, potentially causing a failed
VM-entry. A guest user with access to I/O or the MMIO can use this
flaw to cause a denial of service (system crash) of the guest.

CVE-2014-3673

Liu Wei of Red Hat discovered a flaw in net/core/skbuff.c leading to
a kernel panic when receiving malformed ASCONF chunks. A remote
attacker could use this flaw to crash the system.

CVE-2014-3687

A flaw in the sctp stack was discovered leading to a kernel panic
when receiving duplicate ASCONF chunks. A remote attacker could use
this flaw to crash the system.

CVE-2014-3688

It was found that the sctp stack is prone to a remotely triggerable
memory pressure issue caused by excessive queueing. A remote
attacker could use this flaw to cause denial-of-service conditions
on the system.

CVE-2014-3690

Andy Lutomirski discovered that incorrect register handling in KVM
may lead to denial of service.

CVE-2014-7207

Several Debian developers reported an issue in the IPv6 networking
subsystem. A local user with access to tun or macvtap devices, or a
virtual machine connected to such a device, can cause a denial of
service (system crash).

This update includes a bug fix related to CVE-2014-7207 that disables
UFO (UDP Fragmentation Offload) in the macvtap, tun, and virtio_net
drivers. This will cause migration of a running VM from a host running
an earlier kernel version to a host running this kernel version to fail,
if the VM has been assigned a virtio network device. In order to migrate
such a VM, it must be shut down first.

For the stable distribution (wheezy), these problems have been fixed in
version 3.2.63-2+deb7u1.

We recommend that you upgrade your linux packages.
