"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.

    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.

"Fixes CVEs :

CVE-2012-2123 CVE-2012-2121 CVE-2012-2119

Also fixes a boot regression on some Dell machines Linux 3.3.2

There was a regression at the DVB core, affecting applications that
require the DVB status before having a lock. In order to allow a
broader test (including my environment).

All new patches from the upstream media tree up to Apr, 10 got
backported plus the fix patches, in order to have, among other things,
the az6007 and af9035 drivers backported.

Various bugfixes.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
