______________________________________________________________________________
An update that solves 25 vulnerabilities and has 10 fixes
is now available.
Description:
The SUSE Linux Enterprise 12 GA LTSS kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
- CVE-2015-1350: The VFS subsystem in the Linux kernel provided an
incomplete set of requirements for setattr operations that
underspecifies removing extended privilege attributes, which allowed
local users to cause a denial of service (capability stripping) via a
failed invocation of a system call, as demonstrated by using chown to
remove a capability from the ping or Wireshark dumpcap program
(bnc#914939).
- CVE-2016-2117: The atl2_probe function in
drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly
enabled scatter/gather I/O, which allowed remote attackers to obtain
sensitive information from kernel memory by reading packet data
(bnc#968697).
- CVE-2016-3070: The trace_writeback_dirty_page implementation in
include/trace/events/writeback.h in the Linux kernel improperly
interacted with mm/migrate.c, which allowed local users to cause a
denial of service (NULL pointer dereference and system crash) or
possibly have unspecified other impact by triggering a certain page move
(bnc#979215).
- CVE-2016-5243: The tipc_nl_compat_link_dump function in
net/tipc/netlink_compat.c in the Linux kernel did not properly copy a
certain string, which allowed local users to obtain sensitive
information from kernel stack memory by reading a Netlink message
(bnc#983212).
- CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg
function in net/socket.c in the Linux kernel allowed remote attackers to
execute arbitrary code via vectors involving a recvmmsg system call that
is mishandled during error processing (bnc#1003077).
- CVE-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel mismanages the #BP
and #OF exceptions, which allowed guest OS users to cause a denial of
service (guest OS crash) by declining to handle an exception thrown by
an L2 guest (bnc#1015703).
- CVE-2016-10044: The aio_mount function in fs/aio.c in the Linux kernel
did not properly restrict execute access, which made it easier for local
users to bypass intended SELinux W^X policy restrictions, and
consequently gain privileges, via an io_setup system call (bnc#1023992).
- CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in
the Linux kernel allowed local users to gain privileges or cause a
denial of service (use-after-free) by making multiple bind system calls
without properly ascertaining whether a socket has the SOCK_ZAPPED
status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c
(bnc#1028415).
- CVE-2016-10208: The ext4_fill_super function in fs/ext4/super.c in the
Linux kernel did not properly validate meta block groups, which allowed
physically proximate attackers to cause a denial of service
(out-of-bounds read and system crash) via a crafted ext4 image
(bnc#1023377).
- CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux
kernel is too late in obtaining a certain lock and consequently cannot
ensure that disconnect function calls are safe, which allowed local
users to cause a denial of service (panic) by leveraging access to the
protocol value of IPPROTO_ICMP in a socket system call (bnc#1031003).
- CVE-2017-5669: The do_shmat function in ipc/shm.c in the Linux kernel
did not restrict the address calculated by a certain rounding operation,
which allowed local users to map page zero, and consequently bypass a
protection mechanism that exists for the mmap system call, by making
crafted shmget and shmat system calls in a privileged context
(bnc#1026914).
- CVE-2017-5897: The ip6gre_err function in net/ipv6/ip6_gre.c in the
Linux kernel allowed remote attackers to have unspecified impact via
vectors involving GRE flags in an IPv6 packet, which trigger an
out-of-bounds access (bnc#1023762).
- CVE-2017-5970: The ipv4_pktinfo_prepare function in
net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a
denial of service (system crash) via (1) an application that made
crafted system calls or possibly (2) IPv4 traffic with invalid IP
options (bnc#1024938).
- CVE-2017-5986: Race condition in the sctp_wait_for_sndbuf function in
net/sctp/socket.c in the Linux kernel allowed local users to cause a
denial of service (assertion failure and panic) via a multithreaded
application that peels off an association in a certain buffer-full state
(bnc#1025235).
- CVE-2017-6074: The dccp_rcv_state_process function in net/dccp/input.c
in the Linux kernel mishandled DCCP_PKT_REQUEST packet data structures
in the LISTEN state, which allowed local users to obtain root privileges
or cause a denial of service (double free) via an application that made
an IPV6_RECVPKTINFO setsockopt system call (bnc#1026024).
- CVE-2017-6214: The tcp_splice_read function in net/ipv4/tcp.c in the
Linux kernel allowed remote attackers to cause a denial of service
(infinite loop and soft lockup) via vectors involving a TCP packet with
the URG flag (bnc#1026722).
- CVE-2017-6345: The LLC subsystem in the Linux kernel did not ensure that
a certain destructor exists in required circumstances, which allowed
local users to cause a denial of service (BUG_ON) or possibly have
unspecified other impact via crafted system calls (bnc#1027190).
- CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux
kernel allowed local users to cause a denial of service (use-after-free)
or possibly have unspecified other impact via a multithreaded
application that made PACKET_FANOUT setsockopt system calls
(bnc#1027189).
- CVE-2017-6348: The hashbin_delete function in net/irda/irqueue.c in the
Linux kernel improperly managed lock dropping, which allowed local users
to cause a denial of service (deadlock) via crafted operations on IrDA
devices (bnc#1027178).
- CVE-2017-6353: net/sctp/socket.c in the Linux kernel did not properly
restrict association peel-off operations during certain wait states,
which allowed local users to cause a denial of service (invalid unlock
and double free) via a multithreaded application. NOTE: this
vulnerability exists because of an incorrect fix for CVE-2017-5986
(bnc#1027066).
- CVE-2017-7187: The sg_ioctl function in drivers/scsi/sg.c in the Linux
kernel allowed local users to cause a denial of service (stack-based
buffer overflow) or possibly have unspecified other impact via a large
command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds
write access in the sg_write function (bnc#1030213).
- CVE-2017-7261: The vmw_surface_define_ioctl function in
drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not
check for a zero value of certain levels data, which allowed local users
to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and
possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device
(bnc#1031052).
- CVE-2017-7294: The vmw_surface_define_ioctl function in
drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not
validate addition of certain levels data, which allowed local users to
trigger an integer overflow and out-of-bounds write, and cause a denial
of service (system hang or crash) or possibly gain privileges, via a
crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440).
- CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in
the Linux kernel did not properly validate certain block-size data,
which allowed local users to cause a denial of service (overflow) or
possibly have unspecified other impact via crafted system calls
(bnc#1031579).
- CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind
compat syscalls in mm/mempolicy.c in the Linux kernel allowed local
users to obtain sensitive information from uninitialized stack data by
triggering failure of a certain bitmap operation (bnc#1033336).
