The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-1068: Fixed flaw in the implementation of     32-bit syscall interface for bridging. This allowed a     privileged user to arbitrarily write to a limited range     of kernel memory (bnc#1085107).

  - CVE-2017-18221: The __munlock_pagevec function allowed     local users to cause a denial of service (NR_MLOCK     accounting corruption) via crafted use of mlockall and     munlockall system calls (bnc#1084323).

  - CVE-2018-1066: Prevent NULL pointer dereference in     fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an     attacker controlling a CIFS server to kernel panic a     client that has this server mounted, because an empty     TargetInfo field in an NTLMSSP setup negotiation     response was mishandled during session recovery     (bnc#1083640).

  - CVE-2017-13166: Prevent elevation of privilege     vulnerability in the kernel v4l2 video driver     (bnc#1072865).

  - CVE-2017-16911: The vhci_hcd driver allowed local     attackers to disclose kernel memory addresses.
    Successful exploitation required that a USB device was     attached over IP (bnc#1078674).

  - CVE-2017-15299: The KEYS subsystem mishandled use of     add_key for a key that already exists but is     uninstantiated, which allowed local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     crafted system call (bnc#1063416).

  - CVE-2017-18208: The madvise_willneed function kernel     allowed local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping (bnc#1083494).

  - CVE-2018-7566: The ALSA sequencer core initializes the     event pool on demand by invoking snd_seq_pool_init()     when the first write happens and the pool is empty. A     user could have reset the pool size manually via ioctl     concurrently, which may have lead UAF or out-of-bound     access (bsc#1083483).

  - CVE-2017-18204: The ocfs2_setattr function allowed local     users to cause a denial of service (deadlock) via DIO     requests (bnc#1083244).

  - CVE-2017-16644: The hdpvr_probe function allowed local     users to cause a denial of service (improper error     handling and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1067118).

  - CVE-2018-6927: The futex_requeue function allowed     attackers to cause a denial of service (integer     overflow) or possibly have unspecified other impact by     triggering a negative wake or requeue value     (bnc#1080757).

  - CVE-2017-16914: The 'stub_send_ret_submit()' function     allowed attackers to cause a denial of service (NULL     pointer dereference) via a specially crafted USB over IP     packet (bnc#1078669).

  - CVE-2016-7915: The hid_input_field function allowed     physically proximate attackers to obtain sensitive     information from kernel memory or cause a denial of     service (out-of-bounds read) by connecting a device     (bnc#1010470).

  - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user     functions did unbalanced refcounting when a SCSI I/O     vector had small consecutive buffers belonging to the     same page. The bio_add_pc_page function merged them into     one, but the page reference was never dropped. This     caused a memory leak and possible system lockup     (exploitable against the host OS by a guest OS user, if     a SCSI disk is passed through to a virtual machine) due     to an out-of-memory condition (bnc#1062568).

  - CVE-2017-16912: The 'get_pipe()' function allowed     attackers to cause a denial of service (out-of-bounds     read) via a specially crafted USB over IP packet     (bnc#1078673).

  - CVE-2017-16913: The 'stub_recv_cmd_submit()' function     when handling CMD_SUBMIT packets allowed attackers to     cause a denial of service (arbitrary memory allocation)     via a specially crafted USB over IP packet     (bnc#1078672).

  - CVE-2018-5332: The rds_message_alloc_sgs() function did     not validate a value that is used during DMA page     allocation, leading to a heap-based out-of-bounds write     (related to the rds_rdma_extra_size function in     net/rds/rdma.c) (bnc#1075621).

  - CVE-2018-5333: The rds_cmsg_atomic function in     net/rds/rdma.c mishandled cases where page pinning fails     or an invalid address is supplied, leading to an     rds_atomic_free_op NULL pointer dereference     (bnc#1075617).

  - CVE-2017-18017: The tcpmss_mangle_packet function     allowed remote attackers to cause a denial of service     (use-after-free and memory corruption) or possibly have     unspecified other impact by leveraging the presence of     xt_TCPMSS in an iptables action (bnc#1074488).

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

Additional Changes :

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A use-after-free vulnerability was found in the     kernel's socket recvmmsg subsystem. This may allow     remote attackers to corrupt memory and may allow     execution of arbitrary code. This corruption takes     place during the error handling routines within
    __sys_recvmmsg() function.(CVE-2016-7117)

  - A heap-buffer overflow vulnerability was found in the     arcmsr_iop_message_xfer() function in     'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux     kernel through 4.8.2. The function does not restrict a     certain length field, which allows local users to gain     privileges or cause a denial of service via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can     potentially cause kernel heap corruption and arbitrary     kernel code execution.(CVE-2016-7425)

  - A flaw was found in the Linux kernel's implementation     of seq_file where a local attacker could manipulate     memory in the put() function pointer. This could lead     to memory corruption and possible privileged     escalation.(CVE-2016-7910)

  - A use-after-free vulnerability in sys_ioprio_get() was     found due to get_task_ioprio() accessing the     task-i1/4zio_context without holding the task lock and     could potentially race with exit_io_context(), leading     to a use-after-free.(CVE-2016-7911)

  - The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) via vectors     involving omission of the firmware name from a certain     data structure. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-7913)

  - The assoc_array_insert_into_terminal_node() function in     'lib/assoc_array.c' in the Linux kernel before 4.5.3     does not check whether a slot is a leaf, which allows     local users to obtain sensitive information from kernel     memory or cause a denial of service (invalid pointer     dereference and out-of-bounds read) via an application     that uses associative-array data     structures.(CVE-2016-7914)

  - The hid_input_field() function in     'drivers/hid/hid-core.c' in the Linux kernel before 4.6     allows physically proximate attackers to obtain     sensitive information from kernel memory or cause a     denial of service (out-of-bounds read) by connecting a     device.(CVE-2016-7915)

  - Race condition in the environ_read() function in     'fs/proc/base.c' in the Linux kernel before 4.5.4     allows local users to obtain sensitive information from     kernel memory by reading a '/proc/*/environ' file     during a process-setup time interval in which     environment-variable copying is     incomplete.(CVE-2016-7916)

  - A flaw was found in the Linux networking subsystem     where a local attacker with CAP_NET_ADMIN capabilities     could cause an out-of-bounds memory access by creating     a smaller-than-expected ICMP header and sending to its     destination via sendto().(CVE-2016-8399)

  - Linux kernel built with the Kernel-based Virtual     Machine (CONFIG_KVM) support is vulnerable to a null     pointer dereference flaw. It could occur on x86     platform, when emulating an undefined instruction. An     attacker could use this flaw to crash the host kernel     resulting in DoS.(CVE-2016-8630)

  - A buffer overflow vulnerability due to a lack of input     filtering of incoming fragmented datagrams was found in     the IP-over-1394 driver firewire-net in a fragment     handling code in the Linux kernel. The vulnerability     exists since firewire supported IPv4, i.e. since     version 2.6.31 (year 2009) till version v4.9-rc4. A     maliciously formed fragment with a respectively large     datagram offset would cause a memcpy() past the     datagram buffer, which would cause a system panic or     possible arbitrary code execution.The flaw requires     firewire-net module to be loaded and is remotely     exploitable from connected firewire devices, but not     over a local network.(CVE-2016-8633)

  - It was discovered that the Linux kernel since 3.6-rc1     with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG()     statement in tcp_collapse() function after making a     number of certain syscalls leading to a possible system     crash.(CVE-2016-8645)

  - A vulnerability was found in the Linux kernel. An     unprivileged local user could trigger oops in     shash_async_export() by attempting to force the     in-kernel hashing algorithms into decrypting an empty     data set.(CVE-2016-8646)

  - A flaw was found in the Linux kernel key management     subsystem in which a local attacker could crash the     kernel or corrupt the stack and additional memory     (denial of service) by supplying a specially crafted     RSA key. This flaw panics the machine during the     verification of the RSA key.(CVE-2016-8650)

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets     implementation in the Linux kernel networking subsystem     handled synchronization while creating the TPACKET_V3     ring buffer. A local user able to open a raw packet     socket (requires the CAP_NET_RAW capability) could use     this flaw to elevate their privileges on the     system.(CVE-2016-8655)

  - A flaw was found in the way the Linux kernel's     networking subsystem handled offloaded packets with     multiple layers of encapsulation in the GRO (Generic     Receive Offload) code path. A remote attacker could use     this flaw to trigger unbounded recursion in the kernel     that could lead to stack corruption, resulting in a     system crash.(CVE-2016-8666)

  - A flaw was discovered in the Linux kernel's     implementation of VFIO. An attacker issuing an ioctl     can create a situation where memory is corrupted and     modify memory outside of the expected area. This may     overwrite kernel memory and subvert kernel     execution.(CVE-2016-9083)

  - The use of a kzalloc with an integer multiplication     allowed an integer overflow condition to be reached in     vfio_pci_intrs.c. This combined with CVE-2016-9083 may     allow an attacker to craft an attack and use     unallocated memory, potentially crashing the     machine.(CVE-2016-9084)

  - A flaw was found in the Linux kernel's implementation     of the SCTP protocol. A remote attacker could trigger     an out-of-bounds read with an offset of up to 64kB     potentially causing the system to crash.(CVE-2016-9555)

  - It was found that the blk_rq_map_user_iov() function in     the Linux kernel's block device implementation did not     properly restrict the type of iterator, which could     allow a local attacker to read or write to arbitrary     kernel memory locations or cause a denial of service     (use-after-free) by leveraging write access to a     /dev/sg device.(CVE-2016-9576)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization(nVMX) feature     enabled(nested=1), is vulnerable to an uncaught     exception issue. It could occur if an L2 guest was to     throw an exception which is not handled by an L1     guest.(CVE-2016-9588)

  - It was discovered that root can gain direct access to     an internal keyring, such as '.dns_resolver' in RHEL-7     or '.builtin_trusted_keys' upstream, by joining it as     its session keyring. This allows root to bypass module     signature verification by adding a new public key of     its own devising to the keyring.(CVE-2016-9604)

  - A flaw was found in the Linux kernel's implementation     of XFS file attributes. Two memory leaks were detected     in xfs_attr_shortform_list and xfs_attr3_leaf_list_int     when running a docker container backed by xfs/overlay2.
    A dedicated attacker could possible exhaust all memory     and create a denial of service     situation.(CVE-2016-9685)

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

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The hid_input_field function in drivers/hid/hid-core.c     in the Linux kernel before 4.6 allows physically     proximate attackers to obtain sensitive information     from kernel memory or cause a denial of service     (out-of-bounds read) by connecting a device, as     demonstrated by a Logitech DJ receiver.(CVE-2016-7915)

  - In the Linux kernel through 4.14.13,     drivers/block/loop.c mishandles lo_release     serialization, which allows attackers to cause a denial     of service (__lock_acquire use-after-free) or possibly     have unspecified other impact.(CVE-2018-5344)

  - In the Linux kernel through 4.14.13, the     rds_cmsg_atomic() function in 'net/rds/rdma.c'     mishandles cases where page pinning fails or an invalid     address is supplied by a user. This can lead to a NULL     pointer dereference in rds_atomic_free_op() and thus to     a system panic.(CVE-2018-5333)

  - In the Linux kernel through 4.14.13, the     rds_message_alloc_sgs() function does not validate a     value that is used during DMA page allocation, leading     to a heap-based out-of-bounds write (related to the     rds_rdma_extra_size() function in 'net/rds/rdma.c') and     thus to a system panic. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2018-5332)

  - A flaw was found in the upstream kernel Skcipher     component. This vulnerability affects the     skcipher_recvmsg function of the component Skcipher.
    The manipulation with an unknown input leads to a     privilege escalation vulnerability.(CVE-2017-13215)

  - The tcpmss_mangle_packet function in     net/netfilter/xt_TCPMSS.c in the Linux kernel before     4.11, and 4.9.x before 4.9.36, allows remote attackers     to cause a denial of service (use-after-free and memory     corruption) or possibly have unspecified other impact     by leveraging the presence of xt_TCPMSS in an iptables     action.(CVE-2017-18017)

  - The Salsa20 encryption algorithm in the Linux kernel     before 4.14.8 does not correctly handle zero-length     inputs, allowing a local attacker able to use the     AF_ALG-based skcipher interface     (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of     service (uninitialized-memory free and kernel crash) or     have unspecified other impact by executing a crafted     sequence of system calls that use the blkcipher_walk     API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 were     vulnerable.(CVE-2017-17805)

  - The HMAC implementation (crypto/hmac.c) in the Linux     kernel before 4.14.8 does not validate that the     underlying cryptographic hash algorithm is unkeyed,     allowing a local attacker able to use the AF_ALG-based     hash interface (CONFIG_CRYPTO_USER_API_HASH) and the     SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a     kernel stack buffer overflow by executing a crafted     sequence of system calls that encounter a missing SHA-3     initialization.(CVE-2017-17806)

  - he KEYS subsystem in the Linux kernel before 4.14.6     omitted an access-control check when adding a key to     the current task's 'default request-key keyring' via     the request_key() system call, allowing a local user to     use a sequence of crafted system calls to add keys to a     keyring with only Search permission (not Write     permission) to that keyring, related to     construct_get_dest_keyring() in     security/keys/request_key.c.(CVE-2017-17807)

  - The Linux Kernel 2.6.32 and later are affected by a     denial of service, by flooding the diagnostic port 0x80     an exception can be triggered leading to a kernel     panic.(CVE-2017-1000407)

  - The XFRM dump policy implementation in     net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11     allows local users to gain privileges or cause a denial     of service (use-after-free) via a crafted SO_RCVBUF     setsockopt system call in conjunction with     XFRM_MSG_GETPOLICY Netlink messages.(CVE-2017-16939)

  - The dccp_disconnect function in net/dccp/proto.c in the     Linux kernel through 4.14.3 allows local users to gain     privileges or cause a denial of service     (use-after-free) via an AF_UNSPEC connect system call     during the DCCP_LISTEN state.(CVE-2017-8824)

  - net/netfilter/nfnetlink_cthelper.c in the Linux kernel     through 4.14.4 does not require the CAP_NET_ADMIN     capability for new, get, and del operations, which     allows local users to bypass intended access     restrictions because the nfnl_cthelper_list data     structure is shared across all net     namespaces.(CVE-2017-17448)

  - Use-after-free vulnerability in the snd_pcm_info     function in the ALSA subsystem in the Linux kernel     allows attackers to gain privileges via unspecified     vectors.(CVE-2017-0861)

  - The usb_destroy_configuration function in     drivers/usb/core/config.c in the USB core subsystem in     the Linux kernel through 4.14.5 does not consider the     maximum number of configurations and interfaces before     attempting to release resources, which allows local     users to cause a denial of service (out-of-bounds write     access) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-17558)

  - The __netlink_deliver_tap_skb function in     net/netlink/af_netlink.c in the Linux kernel through     4.14.4, when CONFIG_NLMON is enabled, does not restrict     observations of Netlink messages to a single net     namespace, which allows local users to obtain sensitive     information by leveraging the CAP_NET_ADMIN capability     to sniff an nlmon interface for all Netlink activity on     the system.(CVE-2017-17449)

  - net/netfilter/xt_osf.c in the Linux kernel through     4.14.4 does not require the CAP_NET_ADMIN capability     for add_callback and remove_callback operations, which     allows local users to bypass intended access     restrictions because the xt_osf_fingers data structure     is shared across all net namespaces.(CVE-2017-17450)

  - The bnep_add_connection function in     net/bluetooth/bnep/core.c in the Linux kernel before     3.19 does not ensure that an l2cap socket is available,     which allows local users to gain privileges via a     crafted application.(CVE-2017-15868)

  - The einj_error_inject function in     drivers/acpi/apei/einj.c in the Linux kernel allows     local users to simulate hardware errors and     consequently cause a denial of service by leveraging     failure to disable APEI error injection through EINJ     when securelevel is set.(CVE-2016-3695)

The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-1068: Fixed flaw in the implementation of     32-bit syscall interface for bridging. This allowed a     privileged user to arbitrarily write to a limited range     of kernel memory (bnc#1085107).

  - CVE-2017-18221: The __munlock_pagevec function allowed     local users to cause a denial of service (NR_MLOCK     accounting corruption) via crafted use of mlockall and     munlockall system calls (bnc#1084323).

  - CVE-2018-1066: Prevent NULL pointer dereference in     fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an     attacker controlling a CIFS server to kernel panic a     client that has this server mounted, because an empty     TargetInfo field in an NTLMSSP setup negotiation     response was mishandled during session recovery     (bnc#1083640).

  - CVE-2017-13166: Prevent elevation of privilege     vulnerability in the kernel v4l2 video driver     (bnc#1072865).

  - CVE-2017-16911: The vhci_hcd driver allowed local     attackers to disclose kernel memory addresses.
    Successful exploitation required that a USB device was     attached over IP (bnc#1078674).

  - CVE-2017-15299: The KEYS subsystem mishandled use of     add_key for a key that already exists but is     uninstantiated, which allowed local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     crafted system call (bnc#1063416).

  - CVE-2017-18208: The madvise_willneed function kernel     allowed local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping (bnc#1083494).

  - CVE-2018-7566: The ALSA sequencer core initializes the     event pool on demand by invoking snd_seq_pool_init()     when the first write happens and the pool is empty. A     user could have reset the pool size manually via ioctl     concurrently, which may have lead UAF or out-of-bound     access (bsc#1083483).

  - CVE-2017-18204: The ocfs2_setattr function allowed local     users to cause a denial of service (deadlock) via DIO     requests (bnc#1083244).

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The hid_input_field() function in     'drivers/hid/hid-core.c' in the Linux kernel before 4.6     allows physically proximate attackers to obtain     sensitive information from kernel memory or cause a     denial of service (out-of-bounds read) by connecting a     device.(CVE-2016-7915i1/4%0

  - The Linux kernel, before version 4.14.2, is vulnerable     to a deadlock caused by     fs/ocfs2/file.c:ocfs2_setattr(), as the function does     not wait for DIO requests before locking the inode.
    This can be exploited by local users to cause a     subsequent denial of service.(CVE-2017-18204i1/4%0

  - The vmw_gb_surface_define_ioctl function (accessible     via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel through 4.11.4 defines a backup_handle variable     but does not give it an initial value. If one attempts     to create a GB surface, with a previously allocated DMA     buffer to be used as a backup buffer, the backup_handle     variable does not get written to and is then later     returned to user space, allowing local users to obtain     sensitive information from uninitialized kernel memory     via a crafted ioctl call.(CVE-2017-9605i1/4%0

  - Use-after-free vulnerability in the nfqnl_zcopy     function in net/netfilter/nfnetlink_queue_core.c in the     Linux kernel through 3.13.6 allows attackers to obtain     sensitive information from kernel memory by leveraging     the absence of a certain orphaning operation. NOTE: the     affected code was moved to the skb_zerocopy function in     net/core/skbuff.c before the vulnerability was     announced.(CVE-2014-2568i1/4%0

  - It was found that the Linux kernel's ISO file system     implementation did not correctly limit the traversal of     Rock Ridge extension Continuation Entries (CE). An     attacker with physical access to the system could use     this flaw to trigger an infinite loop in the kernel,     resulting in a denial of service.(CVE-2014-9420i1/4%0

  - An integer overflow vulnerability was found in the     ring_buffer_resize() calculations in which a privileged     user can adjust the size of the ringbuffer message     size. These calculations can create an issue where the     kernel memory allocator will not allocate the correct     count of pages yet expect them to be usable. This can     lead to the ftrace() output to appear to corrupt kernel     memory and possibly be used for privileged escalation     or more likely kernel panic.(CVE-2016-9754i1/4%0

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9730i1/4%0

  - In was found that in the Linux kernel, in     vmw_surface_define_ioctl() function in     'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file, a     'num_sizes' parameter is assigned a user-controlled     value which is not checked if it is zero. This is used     in a call to kmalloc() and later leads to dereferencing     ZERO_SIZE_PTR, which in turn leads to a GPF and     possibly to a kernel panic.(CVE-2017-7261i1/4%0

  - A race condition flaw was found in the way the Linux     kernel keys management subsystem performed key garbage     collection. A local attacker could attempt accessing a     key while it was being garbage collected, which would     cause the system to crash.(CVE-2014-9529i1/4%0

  - A flaw was found in the Linux kernel's implementation     of i8042 serial ports. An attacker could cause a kernel     panic if they are able to add and remove devices as the     module is loaded.(CVE-2017-18079i1/4%0

  - drivers/hid/hid-pl.c in the Human Interface Device     (HID) subsystem in the Linux kernel through 3.11, when     CONFIG_HID_PANTHERLORD is enabled, allows physically     proximate attackers to cause a denial of service     (heap-based out-of-bounds write) via a crafted     device.(CVE-2013-2892i1/4%0

  - The __clear_user function in     arch/arm64/lib/clear_user.S in the Linux kernel before     3.17.4 on the ARM64 platform allows local users to     cause a denial of service (system crash) by reading one     byte beyond a /dev/zero page boundary.(CVE-2014-7843i1/4%0

  - A divide-by-zero vulnerability was found in a way the     kernel processes TCP connections. The error can occur     if a connection starts another cwnd reduction phase by     setting tp-i1/4zprior_cwnd to the current cwnd (0) in     tcp_init_cwnd_reduction(). A remote, unauthenticated     attacker could use this flaw to crash the kernel     (denial of service).(CVE-2016-2070i1/4%0

  - The adjust_branches function in kernel/bpf/verifier.c     in the Linux kernel before 4.5 does not consider the     delta in the backward-jump case, which allows local     users to obtain sensitive information from kernel     memory by creating a packet filter and then loading     crafted BPF instructions.(CVE-2016-2383i1/4%0

  - System using the infiniband support module ib_srpt were     vulnerable to a denial of service by system crash by a     local attacker who is able to abort writes to a device     using this initiator.(CVE-2016-6327i1/4%0

  - A security flaw was found in the Linux kernel in the     mark_source_chains() function in     'net/ipv4/netfilter/ip_tables.c'. It is possible for a     user-supplied 'ipt_entry' structure to have a large     'next_offset' field. This field is not bounds checked     prior to writing to a counter value at the supplied     offset.(CVE-2016-3134i1/4%0

  - An out-of-bounds access issue was discovered in     yurex_read() in drivers/usb/misc/yurex.c in the Linux     kernel. A local attacker could use user access     read/writes with incorrect bounds checking in the yurex     USB driver to crash the kernel or potentially escalate     privileges.(CVE-2018-16276i1/4%0

  - drivers/media/v4l2-core/videobuf2-v4l2.c in the Linux     kernel before 4.5.3 allows local users to cause a     denial of service (kernel memory write operation) or     possibly have unspecified other impact via a crafted     number of planes in a VIDIOC_DQBUF ioctl     call.(CVE-2016-4568i1/4%0

  - The usb_serial_console_disconnect function in     drivers/usb/serial/console.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (use-after-free and system crash) or possibly     have unspecified other impact via a crafted USB device,     related to disconnection and failed     setup.(CVE-2017-16525i1/4%0

  - The Linux kernel is vulnerable to a NULL pointer     dereference in the ext4/xattr.c:ext4_xattr_inode_hash()     function. An attacker could trick a legitimate user or     a privileged attacker could exploit this to cause a     NULL pointer dereference with a crafted ext4 image.

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2012-6704, CVE-2016-9793

Eric Dumazet found that a local user with CAP_NET_ADMIN capability could set a socket's buffer size to be negative, leading to a denial of service or other security impact. Additionally, in kernel versions prior to 3.5, any user could do this if sysctl net.core.rmem_max was changed to a very large value.

CVE-2015-1350 / #770492

Ben Harris reported that local users could remove set-capability attributes from any file visible to them, allowing a denial of service.

CVE-2015-8962

Calvin Owens fouund that removing a SCSI device while it was being accessed through the SCSI generic (sg) driver led to a double- free, possibly causing a denial of service (crash or memory corruption) or privilege escalation. This could be exploited by local users with permision to access a SCSI device node.

CVE-2015-8963

Sasha Levin reported that hot-unplugging a CPU resulted in a use-after-free by the performance events (perf) subsystem, possibly causing a denial of service (crash or memory corruption) or privilege escalation. This could by exploited by any local user.

CVE-2015-8964

It was found that the terminal/serial (tty) subsystem did not reliably reset the terminal buffer state when the terminal line discipline was changed. This could allow a local user with access to a terminal device to read sensitive information from kernel memory.

CVE-2016-7097

Jan Kara found that changing the POSIX ACL of a file never cleared its set-group-ID flag, which should be done if the user changing it is not a member of the group-owner. In some cases, this would allow the user-owner of an executable to gain the privileges of the group-owner.

CVE-2016-7910

Vegard Nossum discovered that a memory allocation failure while handling a read of /proc/diskstats or /proc/partitions could lead to a use-after-free, possibly causing a denial of service (crash or memory corruption) or privilege escalation.

Dmitry Vyukov reported that a race between ioprio_get() and ioprio_set() system calls could result in a use-after-free, possibly causing a denial of service (crash) or leaking sensitive information.

CVE-2016-7915

Benjamin Tissoires found that HID devices could trigger an out-of- bounds memory access in the HID core. A physically present user could possibly use this for denial of service (crash) or to leak sensitive information.

CVE-2016-8399

Qidan He reported that the IPv4 ping socket implementation did not validate the length of packets to be sent. A user with permisson to use ping sockets could cause an out-of-bounds read, possibly resulting in a denial of service or information leak. However, on Debian systems no users have permission to create ping sockets by default.

CVE-2016-8633

Eyal Itkin reported that the IP-over-Firewire driver (firewire-net) did not validate the offset or length in link-layer fragmentation headers. This allowed a remote system connected by Firewire to write to memory after a packet buffer, leading to a denial of service (crash) or remote code execution.

CVE-2016-8645

Marco Grassi reported that if a socket filter (BPF program) attached to a TCP socket truncates or removes the TCP header, this could cause a denial of service (crash). This was exploitable by any local user.

CVE-2016-8655

Philip Pettersson found that the implementation of packet sockets (AF_PACKET family) had a race condition between enabling a transmit ring buffer and changing the version of buffers used, which could result in a use-after-free. A local user with the CAP_NET_ADMIN capability could exploit this for privilege escalation.

CVE-2016-9178

Al Viro found that a failure to read data from user memory might lead to a information leak on the x86 architecture (amd64 or i386).

CVE-2016-9555

Andrey Konovalov reported that the SCTP implementation does not validate 'out of the blue' packet chunk lengths early enough. A remote system able could use this to cause a denial of service (crash) or other security impact for systems using SCTP.

CVE-2016-9576, CVE-2016-10088

Dmitry Vyukov reported that using splice() with the SCSI generic driver led to kernel memory corruption. Local users with permision to access a SCSI device node could exploit this for privilege escalation.

CVE-2016-9756

Dmitry Vyukov reported that KVM for the x86 architecture (amd64 or i386) did not correctly handle the failure of certain instructions that require software emulation on older processors. This could be exploited by guest systems to leak sensitive information or for denial of service (log spam).

CVE-2016-9794

Baozeng Ding reported a race condition in the ALSA (sound) subsystem that could result in a use-after-free. Local users with access to a PCM sound device could exploit this for denial of service (crash or memory corruption) or other security impact.

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.84-1. This version also includes bug fixes from upstream version 3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.
Finally, this version adds the option to mitigate security issues in the performance events (perf) subsystem by disabling use by unprivileged users. This can be done by setting sysctl kernel.perf_event_paranoid=3.

For Debian 8 'Jessie', these problems have been fixed in version 3.16.39-1 which will be included in the next point release (8.6).

We recommend that you upgrade your linux packages.
