kernel: security and bugfix update (important)

The Linux kernel was updated to fix security issues and bugs.

Security issues fixed: CVE-2014-3153: The futex_requeue function in
kernel/futex.c in the Linux kernel did not ensure that calls have two
different futex addresses, which allowed local users to gain privileges
via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter
modification.

CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST
extension implementations in the sk_run_filter function in
net/core/filter.c in the Linux kernel did not check whether a certain
length value is sufficiently large, which allowed local users to cause a
denial of service (integer underflow and system crash) via crafted BPF
instructions. NOTE: the affected code was moved to the __skb_get_nlattr
and __skb_get_nlattr_nest functions before the vulnerability was announced.

CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension implementation in the
sk_run_filter function in net/core/filter.c in the Linux kernel used the
reverse order in a certain subtraction, which allowed local users to cause
a denial of service (over-read and system crash) via crafted BPF
instructions. NOTE: the affected code was moved to the
__skb_get_nlattr_nest function before the vulnerability was announced.

CVE-2014-0077: drivers/vhost/net.c in the Linux kernel, when mergeable
buffers are disabled, did not properly validate packet lengths, which
allowed 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-2014-0055: The get_rx_bufs function in drivers/vhost/net.c in the
vhost-net subsystem in the Linux kernel package did not properly handle
vhost_get_vq_desc errors, which allowed guest OS users to cause a denial
of service (host OS crash) via unspecified vectors.

CVE-2014-2678: The rds_iw_laddr_check function in net/rds/iw.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 via a bind system call for an RDS socket on a system that lacks RDS
transports.

CVE-2013-7339: The rds_ib_laddr_check function in net/rds/ib.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 via a bind system call for an RDS socket on a system that lacks RDS
transports.

CVE-2014-2851: Integer overflow in the ping_init_sock function in
net/ipv4/ping.c in the Linux kernel allowed local users to cause a denial
of service (use-after-free and system crash) or possibly gain privileges
via a crafted application that leverages an improperly managed reference
counter.
