Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. Notable new features :

- Toleration of newer crypto hardware for z Systems

- USB 2.0 Link power management for Haswell-ULT The following security bugs were fixed :

- 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-2017-7184: The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel did not validate certain size data after an XFRM_MSG_NEWAE update, which allowed local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability (bsc#1030573).

- 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 (bsc#1024938).

- 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 (bsc#1033336).

- 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-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-2017-5669: 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-2015-3288: mm/memory.c in the Linux kernel mishandled anonymous pages, which allowed local users to gain privileges or cause a denial of service (page tainting) via a crafted application that triggers writing to page zero (bsc#979021).

- 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-2016-5243: 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-2017-6353: 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 (bnc#1027066)

- 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-2017-6074: 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-2017-5986: 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-2015-8970: crypto/algif_skcipher.c in the Linux kernel did not verify that a setkey operation has been performed on an AF_ALG socket an accept system call is processed, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted application that does not supply a key, related to the lrw_crypt function in crypto/lrw.c (bsc#1008374).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
