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)\n\n - Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support was vulnerable to an incorrect segment selector(SS) value error. The error could occur while loading values into the SS register in long mode. A user or process inside a guest could use this flaw to crash the guest, resulting in DoS or potentially escalate their privileges inside the guest.(CVE-2017-2583)\n\n - arch/x86/kvm/emulate.c in the Linux kernel through 4.9.3 allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free) via a crafted application that leverages instruction emulation for fxrstor, fxsave, sgdt, and sidt.(CVE-2017-2584)\n\n - A reachable assertion failure flaw was found in the Linux kernel built with KVM virtualisation(CONFIG_KVM) support with Virtual Function I/O feature (CONFIG_VFIO) enabled. This failure could occur if a malicious guest device sent a virtual interrupt (guest IRQ) with a larger (i1/4z1024) index value.(CVE-2017-1000252)\n\n - An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire).

Leap 42.1 kernel was updated to 4.1.36 to receive various\nsecurity and bugfixes.\n\nThe following security bugs were fixed :\n\n - CVE-2016-8655: A race condition in the af_packet\n packet_set_ring function could be used by local\n attackers to crash the kernel or gain privileges\n (bsc#1012754).\n\n - CVE-2016-9794: A use-after-free in ALSA pcm could lead\n to crashes or allowed local users to potentially gain\n privileges (bsc#1013533).\n\n - CVE-2015-8962: Double free vulnerability in the\n sg_common_write function in drivers/scsi/sg.c in the\n Linux kernel allowed local users to gain privileges or\n cause a denial of service (memory corruption and system\n crash) by detaching a device during an SG_IO ioctl call\n (bnc#1010501).\n\n - CVE-2016-9178: The __get_user_asm_ex macro in\n arch/x86/include/asm/uaccess.h in the Linux kernel did\n not initialize a certain integer variable, which allowed\n local users to obtain sensitive information from kernel\n stack memory by triggering failure of a get_user_ex call\n (bnc#1008650).\n\n - CVE-2016-7913: The xc2028_set_config function in\n drivers/media/tuners/tuner-xc2028.c in the Linux kernel\n allowed local users to gain privileges or cause a denial\n of service (use-after-free) via vectors involving\n omission of the firmware name from a certain data\n structure (bnc#1010478).\n\n - CVE-2016-9555: The sctp_sf_ootb function in\n net/sctp/sm_statefuns.c in the Linux kernel lacks\n chunk-length checking for the first chunk, which allowed\n remote attackers to cause a denial of service\n (out-of-bounds slab access) or possibly have unspecified\n other impact via crafted SCTP data (bnc#1011685).\n\n - CVE-2015-8963: Race condition in kernel/events/core.c in\n the Linux kernel allowed local users to gain privileges\n or cause a denial of service (use-after-free) by\n leveraging incorrect handling of an swevent data\n structure during a CPU unplug operation (bnc#1010502).\n\n - CVE-2015-8964: The tty_set_termios_ldisc function in\n drivers/tty/tty_ldisc.c in the Linux kernel allowed\n local users to obtain sensitive information from kernel\n memory by reading a tty data structure (bnc#1010507).\n\n - CVE-2016-8646: The hash_accept function in\n crypto/algif_hash.c in the Linux kernel allowed local\n users to cause a denial of service (OOPS) by attempting\n to trigger use of in-kernel hash algorithms for a socket\n that has received zero bytes of data (bnc#1010150).\n\n - CVE-2016-8633: drivers/firewire/net.c in the Linux\n kernel in certain unusual hardware configurations,\n allowed remote attackers to execute arbitrary code via\n crafted fragmented packets (bnc#1008833).\n\n - CVE-2016-8630: The x86_decode_insn function in\n arch/x86/kvm/emulate.c in the Linux kernel, when KVM is\n enabled, allowed local users to cause a denial of\n service (host OS crash) via a certain use of a ModR/M\n byte in an undefined instruction (bnc#1009222).\n\n - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux\n kernel allowed local users to bypass integer overflow\n checks, and cause a denial of service (memory\n corruption) or have unspecified other impact, by\n leveraging access to a vfio PCI device file for a\n VFIO_DEVICE_SET_IRQS ioctl call, aka a 'state machine\n confusion bug (bnc#1007197).\n\n - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the\n Linux kernel misuses the kzalloc function, which allowed\n local users to cause a denial of service (integer\n overflow) or have unspecified other impact by leveraging\n access to a vfio PCI device file (bnc#1007197).\n\n - CVE-2016-7042: The proc_keys_show function in\n security/keys/proc.c in the Linux kernel through 4.8.2,\n when the GNU Compiler Collection (gcc) stack protector\n is enabled, uses an incorrect buffer size for certain\n timeout data, which allowed local users to cause a\n denial of service (stack memory corruption and panic) by\n reading the /proc/keys file (bnc#1004517).\n\n - CVE-2016-7097: The filesystem implementation in the\n Linux kernel preserves the setgid bit during a setxattr\n call, which allowed local users to gain group privileges\n by leveraging the existence of a setgid program with\n restrictions on execute permissions (bnc#995968).\n\n - CVE-2015-8956: The rfcomm_sock_bind function in\n net/bluetooth/rfcomm/sock.c in the Linux kernel allowed\n local users to obtain sensitive information or cause a\n denial of service (NULL pointer dereference) via vectors\n involving a bind system call on a Bluetooth RFCOMM\n socket (bnc#1003925).\n\nThe following non-security bugs were fixed :\n\n - ata: ahci_xgene: dereferencing uninitialized pointer in\n probe (bsc#1006580).\n\n - blacklist.conf: add some commits (bsc#1006580)\n\n - bna: Add synchronization for tx ring (bsc#993739).\n\n - bonding: set carrier off for devices created through\n netlink (bsc#999577).\n\n - btrfs: deal with duplicates during extent_map insertion\n in btrfs_get_extent (bsc#1001171).\n\n - btrfs: deal with existing encompassing extent map in\n btrfs_get_extent() (bsc#1001171).\n\n - btrfs: fix extent tree corruption due to relocation\n (bsc#990384).\n\n - btrfs: fix races on root_log_ctx lists (bsc#1007653).\n\n - ext4: fix data exposure after a crash (bsc#1012876).\n\n - ext4: fix reference counting bug on block allocation\n error (bsc#1012876).\n\n - gre: Disable segmentation offloads w/ CSUM and we are\n encapsulated via FOU (bsc#1001486).\n\n - gro: Allow tunnel stacking in the case of FOU/GUE\n (bsc#1001486).\n\n - ipv6: send NEWLINK on RA managed/otherconf changes\n (bsc#934067).\n\n - ipv6: send only one NEWLINK when RA causes changes\n (bsc#934067).\n\n - isofs: Do not return EACCES for unknown filesystems\n (bsc#1012876).\n\n - jbd2: fix checkpoint list cleanup (bsc#1012876).\n\n - jbd2: Fix unreclaimed pages after truncate in\n data=journal mode (bsc#1010909).\n\n - locking/static_key: Fix concurrent static_key_slow_inc()\n (bsc#1006580).\n\n - mmc: Fix kabi breakage of mmc-block in 4.1.36\n (stable-4.1.36).\n\n - posix_acl: Added fix for f2fs.\n\n - Revert 'kbuild: add -fno-PIE' (stable-4.1.36).\n\n - Revert 'x86/mm: Expand the exception table logic to\n allow new handling options' (stable-4.1.36).\n\n - tunnels: Remove encapsulation offloads on decap\n (bsc#1001486).\n\n - usbhid: add ATEN CS962 to list of quirky devices\n (bsc#1007615).\n\n - vmxnet3: Wake queue from reset work (bsc#999907).\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.opensuse.org/show_bug.cgi?id=1001171\"\n );\n

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\n __sys_recvmmsg() function.(CVE-2016-7117)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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.\n A dedicated attacker could possible exhaust all memory and create a denial of service situation.(CVE-2016-9685)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

(CVE-2016-9083, Important)\n\n * The use of a kzalloc with an integer multiplication allowed an integer\noverflow condition to be reached in vfio_pci_intrs.c. This combined with\nCVE-2016-9083 may allow an attacker to craft an attack and use unallocated\nmemory, potentially crashing the machine. (CVE-2016-9084, Moderate)\n\nRed Hat would like to thank Philip Pettersson for reporting CVE-2016-8655.\n\nAdditional Changes:\n\nSpace precludes documenting all of the bug fixes and enhancements included\nin this advisory.

Additionally, an out-of-bounds memory access flaw, CVE-2014-7826, was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges.(CVE-2014-7826)\n\nLinux 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)\n\nA flaw was found in the Linux kernel's ext4 filesystem.

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)\n\nA 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)\n\nA flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer.

Because of this, when the code was executed from the exception context, a bug warning appeared on the console. With this update, the regular wait queue and spinlock code in this area has been modified to use simple-wait-queue and raw-spinlocks. This code change enables the asynchronous page fault code to run in a non-preemptable state without bug warnings.

CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the Linux kernel\n misuses the kzalloc function, which allowed local users to cause a\n denial of service (integer overflow) or have unspecified other impact by\n leveraging access to a vfio PCI device file (bnc#1007197).\n - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in\n the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc)\n stack protector is enabled, uses an incorrect buffer size for certain\n timeout data, which allowed local users to cause a denial of service\n (stack memory corruption and panic) by reading the /proc/keys file\n (bnc#1004517).\n - CVE-2016-7097: The filesystem implementation in the Linux kernel\n preserves the setgid bit during a setxattr call, which allowed local\n users to gain group privileges by leveraging the existence of a setgid\n program with restrictions on execute permissions (bnc#995968).\n - CVE-2015-8956: The rfcomm_sock_bind function in\n net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to\n obtain sensitive information or cause a denial of service (NULL pointer\n dereference) via vectors involving a bind system call on a Bluetooth\n RFCOMM socket (bnc#1003925).\n\n The following non-security bugs were fixed:\n\n - ata: ahci_xgene: dereferencing uninitialized pointer in probe\n (bsc#1006580).\n - blacklist.conf: add some commits (bsc#1006580)\n - bna: Add synchronization for tx ring (bsc#993739).\n - bonding: set carrier off for devices created through netlink\n (bsc#999577).\n - btrfs: deal with duplicates during extent_map insertion in\n btrfs_get_extent (bsc#1001171).\n - btrfs: deal with existing encompassing extent map in btrfs_get_extent()\n (bsc#1001171).\n - btrfs: fix extent tree corruption due to relocation (bsc#990384).\n - btrfs: fix races on root_log_ctx lists (bsc#1007653).\n - ext4: fix data exposure after a crash (bsc#1012876).\n - ext4: fix reference counting bug on block allocation error (bsc#1012876).\n - gre: Disable segmentation offloads w/ CSUM and we are encapsulated via\n FOU (bsc#1001486).\n - gro: Allow tunnel stacking in the case of FOU/GUE (bsc#1001486).\n - ipv6: send NEWLINK on RA managed/otherconf changes (bsc#934067).\n - ipv6: send only one NEWLINK when RA causes changes (bsc#934067).\n - isofs: Do not return EACCES for unknown filesystems (bsc#1012876).\n - jbd2: fix checkpoint list cleanup (bsc#1012876).\n - jbd2: Fix unreclaimed pages after truncate in data=journal mode\n (bsc#1010909).\n - locking/static_key: Fix concurrent static_key_slow_inc() (bsc#1006580).\n - mmc: Fix kabi breakage of mmc-block in 4.1.36 (stable-4.1.36).\n - posix_acl: Added fix for f2fs.\n - Revert "kbuild: add -fno-PIE" (stable-4.1.36).\n - Revert "x86/mm: Expand the exception table logic to allow new handling\n options" (stable-4.1.36).\n - tunnels: Remove encapsulation offloads on decap (bsc#1001486).\n - usbhid: add ATEN CS962 to list of quirky devices (bsc#1007615).\n - vmxnet3: Wake queue from reset work (bsc#999907).\n\n", "cvss3": {}, "published": "2016-12-08T15:07:13", "type": "suse", "title": "Security update for the Linux Kernel (important)", "bulletinFamily": "unix", "cvss2": {}, "cvelist": ["CVE-2016-7097", "CVE-2016-9794", "CVE-2016-8633", "CVE-2016-8655", "CVE-2016-9084", "CVE-2015-8962", "CVE-2015-8964", "CVE-2016-9555", "CVE-2016-8630", "CVE-2016-9178", "CVE-2015-8963", "CVE-2016-9083", "CVE-2015-8956", "CVE-2016-8646", "CVE-2016-7913", "CVE-2016-7042"], "modified": "2016-12-08T15:07:13", "id": "OPENSUSE-SU-2016:3058-1", "href": "http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00027.html", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}]}
