The openSUSE 13.2 kernel was updated to receive various security and bugfixes.

Following security bugs were fixed:
- CVE-2016-0728: A reference leak in keyring handling with
join_session_keyring() could lead to local attackers gain root
privileges. (bsc#962075).
- CVE-2015-7550: A local user could have triggered a race between read and
revoke in keyctl (bnc#958951).
- CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions
in drivers/net/ppp/pptp.c in the Linux kernel did not verify an address
length, which allowed local users to obtain sensitive information from
kernel memory and bypass the KASLR protection mechanism via a crafted
application (bnc#959190).
- CVE-2015-8543: The networking implementation in the Linux kernel
did not validate protocol identifiers for certain protocol families,
which allowed local users to cause a denial of service (NULL function
pointer dereference and system crash) or possibly gain privileges by
leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application
(bnc#958886).
- CVE-2014-8989: The Linux kernel did not properly restrict dropping
of supplemental group memberships in certain namespace scenarios,
which allowed local users to bypass intended file permissions by
leveraging a POSIX ACL containing an entry for the group category
that is more restrictive than the entry for the other category, aka a
"negative groups" issue, related to kernel/groups.c, kernel/uid16.c,
and kernel/user_namespace.c (bnc#906545).
- CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux kernel on
the x86_64 platform mishandles IRET faults in processing NMIs that
occurred during userspace execution, which might allow local users to
gain privileges by triggering an NMI (bnc#937969).
- CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in
the Linux kernel through 4.2.3 did not ensure that certain slot numbers
are valid, which allowed local users to cause a denial of service (NULL
pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl
call (bnc#949936).
- CVE-2015-8104: The KVM subsystem in the Linux kernel through 4.2.6,
and Xen 4.3.x through 4.6.x, allowed guest OS users to cause a denial
of service (host OS panic or hang) by triggering many #DB (aka Debug)
exceptions, related to svm.c (bnc#954404).
- CVE-2015-5307: The KVM subsystem in the Linux kernel through 4.2.6,
and Xen 4.3.x through 4.6.x, allowed guest OS users to cause a denial
of service (host OS panic or hang) by triggering many #AC (aka Alignment
Check) exceptions, related to svm.c and vmx.c (bnc#953527).
- CVE-2014-9529: Race condition in the key_gc_unused_keys function in
security/keys/gc.c in the Linux kernel allowed local users to cause
a denial of service (memory corruption or panic) or possibly have
unspecified other impact via keyctl commands that trigger access to
a key structure member during garbage collection of a key (bnc#912202).
- CVE-2015-7990: Race condition in the rds_sendmsg function in
net/rds/sendmsg.c in the Linux kernel allowed local users to cause
a denial of service (NULL pointer dereference and system crash) or
possibly have unspecified other impact by using a socket that was not
properly bound. NOTE: this vulnerability exists because of an incomplete
fix for CVE-2015-6937 (bnc#952384 953052).
- CVE-2015-6937: The __rds_conn_create function in net/rds/connection.c
in the Linux kernel allowed local users to cause a denial of service
(NULL pointer dereference and system crash) or possibly have unspecified
other impact by using a socket that was not properly bound (bnc#945825).
- CVE-2015-7885: The dgnc_mgmt_ioctl function in
drivers/staging/dgnc/dgnc_mgmt.c in the Linux kernel through 4.3.3 did
not initialize a certain structure member, which allowed local users to
obtain sensitive information from kernel memory via a crafted application
(bnc#951627).
- CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in the Linux
kernel did not validate attempted changes to the MTU value, which allowed
context-dependent attackers to cause a denial of service (packet loss)
via a value that is (1) smaller than the minimum compliant value or
(2) larger than the MTU of an interface, as demonstrated by a Router
Advertisement (RA) message that is not validated by a daemon, a different
vulnerability than CVE-2015-0272. NOTE: the scope of CVE-2015-0272 is
limited to the NetworkManager product (bnc#955354).
- CVE-2015-8767: A case can occur when sctp_accept() is called by the
user during a heartbeat timeout event after the 4-way handshake. Since
sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the
bh_sock_lock in sctp_generate_heartbeat_event() will be taken with the
listening socket but released with the new association socket. The result
is a deadlock on any future attempts to take the listening socket lock. (bsc#961509)
- CVE-2015-8575: Validate socket address length in sco_sock_bind() to
prevent information leak (bsc#959399).
- CVE-2015-8551, CVE-2015-8552: xen/pciback: For
XEN_PCI_OP_disable_msi[|x] only disable if device has MSI(X) enabled
(bsc#957990).
- CVE-2015-8550: Compiler optimizations in the XEN PV backend drivers
could have lead to double fetch vulnerabilities, causing denial of
service or arbitrary code execution (depending on the configuration)
(bsc#957988).

- ipv6: fix tunnel error handling (bsc#952579).
- route: Use ipv4_mtu instead of raw rt_pmtu (bsc#955224).
