Description:

 

 

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.74 to receive

various security and bugfixes.

 

Notable new/improved features:

- Improved support for Hyper-V

- Support for the tcp_westwood TCP scheduling algorithm

 

The following security bugs were fixed:

 

- CVE-2017-8106: The handle_invept function in arch/x86/kvm/vmx.c in the

Linux kernel allowed privileged KVM guest OS users to cause a denial of

service (NULL pointer dereference and host OS crash) via a

single-context INVEPT instruction with a NULL EPT pointer (bsc#1035877).

security/keys/keyring.c in the Linux kernel allowed local users to cause

a denial of service (NULL pointer dereference and OOPS) via a

request_key system call for the "dead" type. (bsc#1029850).

- CVE-2017-2647: The KEYS subsystem in the Linux kernel allowed local

users to gain privileges or cause a denial of service (NULL pointer

dereference and system crash) via vectors involving a NULL value for a

certain match field, related to the keyring_search_iterator function in

keyring.c. (bsc#1030593)

- CVE-2016-9604: This fixes handling of keyrings starting with '.' in

KEYCTL_JOIN_SESSION_KEYRING, which could have allowed local users to

manipulate privileged keyrings (bsc#1035576)

- 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).

- CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux

kernel allowed remote attackers to cause a denial of service (system

crash) via a long RPC reply, related to net/sunrpc/svc.c,

fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. (bsc#1034670).

- 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-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux

kernel was too late in obtaining a certain lock and consequently could

not 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-2017-7294: 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-2017-7261: 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-2017-7187: The sg_ioctl function in drivers/scsi/sg.c in the Linux

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-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel mismanaged 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 (bsc#1015703).

- 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-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)

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-2017-5897: 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 (bsc#1023762).

- CVE-2017-5986: A 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

(bsc#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-2016-9191: The cgroup offline implementation in the Linux kernel

mishandled certain drain operations, which allowed local users to cause

a denial of service (system hang) by leveraging access to a container

environment for executing a crafted application (bnc#1008842)

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-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-2016-3070: The trace_writeback_dirty_page implementation in

include/trace/events/writeback.h in the Linux kernel improperly

interacts 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-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-2017-6353: 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-2017-5986: 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

(bsc#1025235).

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-2016-2117: The atl2_probe function in

drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly

enables scatter/gather I/O, which allowed remote attackers to obtain

sensitive information from kernel memory by reading packet data

(bnc#968697)

- 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

(bsc#914939).

- CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg

function in net/socket.c in the Linux kernel allowed remote attackers to
