Security update for Linux kernel (important)

The SUSE Linux Enterprise 11 Service Pack 3 Real Time Extension kernel has
been updated to fix various bugs and security issues.

The following security bugs have been fixed:

   *

     CVE-2012-2372: The rds_ib_xmit function in net/rds/ib_send.c in the

Reliable Datagram Sockets (RDS) protocol implementation in the Linux
kernel 3.7.4 and earlier allows local users to cause a denial of service
(BUG_ON and kernel panic) by establishing an RDS connection with the
source IP address equal to the IPoIB interfaces own IP address, as
demonstrated by rds-ping. (bnc#767610)

   *

     CVE-2013-2929: The Linux kernel before 3.12.2 does not properly use

the get_dumpable function, which allows local users to bypass intended
ptrace restrictions or obtain sensitive information from IA64 scratch
registers via a crafted application, related to kernel/ptrace.c and
arch/ia64/include/asm/processor.h. (bnc#847652)

   *

     CVE-2013-4299: Interpretation conflict in

drivers/md/dm-snap-persistent.c in the Linux kernel through 3.11.6 allows
remote authenticated users to obtain sensitive information or modify data
via a crafted mapping to a snapshot block device. (bnc#846404)

   *

drivers/net/wireless/ath/ath9k/htc_drv_main.c in the Linux kernel through
3.12 uses a BSSID masking approach to determine the set of MAC addresses
on which a Wi-Fi device is listening, which allows remote attackers to
discover the original MAC address after spoofing by sending a series of
packets to MAC addresses with certain bit manipulations. (bnc#851426)

   *

     CVE-2013-6382: Multiple buffer underflows in the XFS implementation

in the Linux kernel through 3.12.1 allow local users to cause a denial of
service (memory corruption) or possibly have unspecified
other impact by leveraging the CAP_SYS_ADMIN capability for a (1)
XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call
with a crafted length value, related to the xfs_attrlist_by_handle
function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle
function in fs/xfs/xfs_ioctl32.c. (bnc#852553)

   *

service (host OS crash) via unspecified vectors. (bnc#870173)

   *

     CVE-2014-0077: drivers/vhost/net.c in the Linux kernel before

3.13.10, when mergeable buffers are disabled, does not properly validate
packet lengths, which allows 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. (bnc#870576)

   *

     CVE-2014-0101: The sctp_sf_do_5_1D_ce function in

net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not
validate certain auth_enable and auth_capable fields before making an
sctp_sf_authenticate call, which allows remote attackers to cause a denial
of service (NULL pointer dereference and system crash) via an SCTP
handshake with a modified INIT chunk and a crafted AUTH chunk before a
COOKIE_ECHO chunk. (bnc#866102)

   *

     CVE-2014-0131: Use-after-free vulnerability in the skb_segment

function in net/core/skbuff.c in the Linux kernel through 3.13.6 allows

   *

     CVE-2014-2309: The ip6_route_add function in net/ipv6/route.c in the

Linux kernel through 3.13.6 does not properly count the addition of
routes, which allows remote attackers to cause a denial of service (memory
consumption) via a flood of ICMPv6 Router Advertisement packets.
(bnc#867531)

   *

     CVE-2014-2523: net/netfilter/nf_conntrack_proto_dccp.c in the Linux

kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows
remote attackers to cause a denial of service (system crash)
or possibly execute arbitrary code via a DCCP packet that triggers a
call to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error function.
(bnc#868653)

   *

     CVE-2014-2678: The rds_iw_laddr_check function in net/rds/iw.c in

     CVE-2014-3122: The try_to_unmap_cluster function in mm/rmap.c in the

Linux kernel before 3.14.3 does not properly consider which pages must be
locked, which allows local users to cause a denial of service (system
crash) by triggering a memory-usage pattern that requires removal of
page-table mappings. (bnc#876102)

   *

     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 through 3.14.3 do not
check whether a certain length value is sufficiently large, which allows
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. (bnc#877257)

   *

     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
