<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).
- CVE-2017-6951: The keyring_search_aux function in 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 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-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)
- 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-2017-5897: 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)
- 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-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).
- 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-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 execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bsc#1003077).
The following non-security bugs were fixed:
- ACPI / APEI: Fix NMI notification handling (bsc#917630).
- arch: Mass conversion of smp_mb__*() (bsc#1020795).
- asm-generic: add __smp_xxx wrappers (bsc#1020795).
- block: remove struct request buffer member (bsc#1020795).
- block: submit_bio_wait() conversions (bsc#1020795).
- bonding: Advertize vxlan offload features when supported (bsc#1009682).
- bonding: handle more gso types (bsc#1009682).
- bonding: use the correct ether type for alb (bsc#1028595).
