openSUSE Security Update : kernel (openSUSE-SU-2014:0856-1)

This script is Copyright (C) 2014-2015 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

Description :

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-2014-0077: 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.

CVE-2014-3122: The try_to_unmap_cluster function in mm/rmap.c in the
Linux kernel did not properly consider which pages must be locked,
which allowed local users to cause a denial of service (system crash)
by triggering a memory-usage pattern that requires removal of
page-table mappings.

Bugs fixed :

- memcg: deprecate memory.force_empty knob (bnc#878274).
