"Description of changes:

* CVE-2012-2123: Privilege escalation when assigning permissions using 
fcaps.

If a process increases permissions using fcaps, all of the dangerous
personality flags which are cleared for suid apps are not cleared. This has
allowed programs that gained elevated permissions using fcaps to disable
the address space randomization of other processes.


* CVE-2012-2121: Memory leak in KVM device assignment.

KVM uses memory slots to track and map guest regions of memory.  When device
assignment is used, the pages backing these slots are pinned in memory 
and mapped
into the iommu.  The problem is that when a memory slot is destroyed the 
pages
for the associated memory slot are neither unpinned nor unmapped from 
the iommu.


* Memory corruption in KVM device assignment slot handling.

A race condition in the KVM device assignment slot handling caused by
missing locks around the unmapping of memory slots could cause a memory
corruption.


* CVE-2012-2136: Privilege escalation in TUN/TAP virtual device.

The length of packet fragments to be sent wasn't validated before use,
leading to heap overflow. A user having access to TUN/TAP virtual
device could use this flaw to crash the system or to potentially
escalate their privileges.


* CVE-2012-2137: Buffer overflow in KVM MSI routing entry handler.

A buffer overflow flaw was found in the setup_routing_entry() function 
in the
KVM subsystem of the Linux kernel in the way the Message Signaled Interrupts
(MSI) routing entry was handled. A local, unprivileged user could use 
this flaw
to cause a denial of service or, possibly, escalate their privileges.


* CVE-2012-1179 and CVE-2012-2373: Hugepage denial of service.

CVE-2012-1179: Denial of service in page mapping of the hugepage subsystem.

In some cases, the hugepage subsystem would allocate new PMDs when not
expected by the memory management subsystem. A privileged user in the
KVM guest can use this flaw to crash the host, an unprivileged local
user could use this flaw to crash the system.

CVE-2012-2373: Denial of service in PAE page tables.

On a PAE system, a non-atomic load could be corrupted by a page fault
resulting in a kernel crash, triggerable by an unprivileged user.


* Regression in handling of bind() with AF_UNSPEC family sockets.

Legacy applications used to bind() with AF_UNSPEC instead of AF_INET. Allow
them to continue doing so, but verify that the address is indeed INADDR_ANY.

"The SUSE Linux Enterprise 11 SP2 kernel was updated to 3.0.34, fixing
a lot of bugs and security issues.

The update from Linux kernel 3.0.31 to 3.0.34 also fixes various bugs
not listed here.

The following security issues have been fixed :

  - Local attackers could trigger an overflow in
    sock_alloc_send_pksb(), potentially crashing the machine
    or escalate privileges. (CVE-2012-2136)

  - A memory leak in transparent hugepages on mmap failure
    could be used by local attacker to run the machine out
    of memory (local denial of service). (CVE-2012-2390)

  - A malicious guest driver could overflow the host stack
    by passing a long descriptor, so potentially crashing
    the host system or escalating privileges on the host.
    (CVE-2012-2119)

  - Malicious NFS server could crash the clients when more
    than 2 GETATTR bitmap words are returned in response to
    the FATTR4_ACL attribute requests, only incompletely
    fixed by CVE-2011-4131. (CVE-2012-2375)

The following non-security bugs have been fixed :

Hyper-V :

  - storvsc: Properly handle errors from the host.
    (bnc#747404)

  - HID: hid-hyperv: Do not use hid_parse_report() directly.

  - HID: hyperv: Set the hid drvdata correctly.

  - drivers/hv: Get rid of an unnecessary check in
    vmbus_prep_negotiate_resp().

  - drivers/hv: util: Properly handle version negotiations.

  - hv: fix return type of hv_post_message().

  - net/hyperv: Add flow control based on hi/low watermark.

  - usb/net: rndis: break out <1/rndis.h> defines. only
    net/hyperv part

  - usb/net: rndis: remove ambiguous status codes. only
    net/hyperv part

  - usb/net: rndis: merge command codes. only net/hyperv
    part

  - net/hyperv: Adding cancellation to ensure rndis filter
    is closed.

  - update hv drivers to 3.4-rc1, requires new 
hv_kvp_daemon :

  - drivers: hv: kvp: Add/cleanup connector defines.

  - drivers: hv: kvp: Move the contents of hv_kvp.h to
    hyperv.h.

  - net/hyperv: Convert camel cased variables in
    rndis_filter.c to lower cases.

  - net/hyperv: Correct the assignment in
    netvsc_recv_callback().

  - net/hyperv: Remove the unnecessary memset in
    rndis_filter_send().

  - drivers: hv: Cleanup the kvp related state in hyperv.h.

  - tools: hv: Use hyperv.h to get the KVP definitions.

  - drivers: hv: kvp: Cleanup the kernel/user protocol.

  - drivers: hv: Increase the number of VCPUs supported in
    the guest.

  - net/hyperv: Fix data corruption in
    rndis_filter_receive().

  - net/hyperv: Add support for vlan trunking from guests.

  - Drivers: hv: Add new message types to enhance KVP.

  - Drivers: hv: Support the newly introduced KVP messages
    in the driver.

  - Tools: hv: Fully support the new KVP verbs in the user
    level daemon.

  - Tools: hv: Support enumeration from all the pools.

  - net/hyperv: Fix the code handling tx busy.

  - patches.suse/suse-hv-pata_piix-ignore-disks.patch
    replace our version of this patch with upstream variant:
