The following security bugs were fixed: CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network could use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service. (bnc#1096748).

CVE-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol. (bnc#1096748).

CVE-2016-8636: Integer overflow in the mem_check_range function in drivers/infiniband/sw/rxe/rxe_mr.c allowed local users to cause a denial of service (memory corruption), obtain sensitive information or possibly have unspecified other impact via a write or read request involving the 'RDMA protocol over infiniband' (aka Soft RoCE) technology (bnc#1024908).

CVE-2017-18174: In the amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function, leading to a double free (bnc#1080533).

CVE-2018-1091: In the flush_tmregs_to_thread function in arch/powerpc/kernel/ptrace.c, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erroneous use of transactional memory (TM) instructions in the core dump path, leading to a denial of service (bnc#1087231).

CVE-2018-1120: By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which made a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks) (bnc#1093158). </pid></pid>

CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c has multiple race conditions (bnc#1133188).

CVE-2019-3882: A flaw was found in the vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS) (bsc#1131427).

CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841).

CVE-2017-17741: The KVM implementation allowed attackers to obtain potentially sensitive information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h (bnc#1073311).

CVE-2019-9503, CVE-2019-8564: Multiple brcmfmac frame validation bypasses have been fixed (bnc#1132828, bnc#1132673).

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

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 kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):The walk_hugetlb_range()     function in 'mm/pagewalk.c' file in the Linux kernel     from v4.0-rc1 through v4.15-rc1 mishandles holes in     hugetlb ranges. This allows local users to obtain     sensitive information from uninitialized kernel memory     via crafted use of the mincore() system     call.(CVE-2017-16994)In the Linux kernel before 4.7,     the amd_gpio_remove function in     drivers/pinctrl/pinctrl-amd.c calls the     pinctrl_unregister function, leading to a double     free.(CVE-2017-18174)In the Linux kernel through     4.20.11, af_alg_release() in crypto/af_alg.c neglects     to set a NULL value for a certain structure member,     which leads to a use-after-free in     sockfs_setattr.(CVE-2019-8912)A security flaw was found     in the Linux kernel that an attempt to move page mapped     by AIO ring buffer to the other node triggers NULL     pointer dereference at trace_writeback_dirty_page(),     because aio_fs_backing_dev_info.dev is     0.(CVE-2016-3070)The NFSv4 implementation in the Linux     kernel through 4.11.1 allows local users to cause a     denial of service (resource consumption) by leveraging     improper channel callback shutdown when unmounting an     NFSv4 filesystem, aka a 'module reference and kernel     daemon' leak.(CVE-2017-9059)When creating audit records     for parameters to executed children processes, an     attacker can convince the Linux kernel audit subsystem     can create corrupt records which may allow an attacker     to misrepresent or evade logging of executing     commands.(CVE-2016-6136)A use-after-free vulnerability     was found in a network namespaces code affecting the     Linux kernel since v4.0-rc1 through v4.15-rc5. The     function get_net_ns_by_id() does not check for the     net::count value after it has found a peer network in     netns_ids idr which could lead to double free and     memory corruption. This vulnerability could allow an     unprivileged local user to induce kernel memory     corruption on the system, leading to a crash. Due to     the nature of the flaw, privilege escalation cannot be     fully ruled out, although it is thought to be     unlikely.(CVE-2017-15129)A NULL pointer dereference     flaw was found in the rds_ib_laddr_check() function in     the Linux kernel's implementation of Reliable Datagram     Sockets (RDS). A local, unprivileged user could use     this flaw to crash the system.(CVE-2013-7339)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)The uio_mmap_physical function     in drivers/uio/uio.c in the Linux kernel before 3.12     does not validate the size of a memory block, which     allows local users to cause a denial of service (memory     corruption) or possibly gain privileges via crafted     mmap operations, a different vulnerability than     CVE-2013-4511.(CVE-2013-6763)In the Linux kernel before     4.20.5, attackers can trigger a     drivers/char/ipmi/ipmi_msghandler.c use-after-free and     OOPS by arranging for certain simultaneous execution of     the code, as demonstrated by a 'service ipmievd     restart' loop.(CVE-2019-9003)An integer overflow flaw     was found in the way the Linux kernel randomized the     stack for processes on certain 64-bit architecture     systems, such as x86-64, causing the stack entropy to     be reduced by four.(CVE-2015-1593)The     compat_sys_recvmmsg function in net/compat.c in the     Linux kernel before 3.13.2, when CONFIG_X86_X32 is     enabled, allows local users to gain privileges via a     recvmmsg system call with a crafted timeout pointer     parameter.(CVE-2014-0038)The kill_something_info     function in kernel/signal.c in the Linux kernel before     4.13, when an unspecified architecture and compiler is     used, might allow local users to cause a denial of     service via an INT_MIN     argument.(CVE-2018-10124)arch/s390/kernel/head64.S in     the Linux kernel before 3.13.5 on the s390 platform     does not properly handle attempted use of the linkage     stack, which allows local users to cause a denial of     service (system crash) by executing a crafted     instruction.(CVE-2014-2039)A flaw was found in the     Linux kernel in that the aoedisk_debugfs_show()     function in drivers/block/aoe/aoeblk.c allows local     users to obtain some kernel address information by     reading a debugfs file. This address is not useful to     commit a further attack.(CVE-2018-7754)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 can reset the pool size     manually via ioctl concurrently, and this may lead to     UAF or out-of-bound access.(CVE-2018-7566)In the     function wmi_set_ie(), the length validation code does     not handle unsigned integer overflow properly. As a     result, a large value of the 'ie_len' argument can     cause a buffer overflow in all Android releases from     CAF (Android for MSM, Firefox OS for MSM, QRD Android)     using the Linux Kernel.(CVE-2018-5848)The Linux kernel     does not properly initialize memory in messages passed     between virtual guests and the host operating system in     the vhost/vhost.c:vhost_new_msg() function. This can     allow local privileged users to read some kernel memory     contents when reading from the /dev/vhost-net device     file.(CVE-2018-1118)Systems with microprocessors     utilizing speculative execution and speculative     execution of memory reads before the addresses of all     prior memory writes are known may allow unauthorized     disclosure of information to an attacker with local     user access via a side-channel analysis, aka     Speculative Store Bypass (SSB), Variant     4.(CVE-2018-3639)

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-4315 advisory.    - In all Qualcomm products with Android releases from CAF using the Linux kernel, during DMA allocation, due     to wrong data type of size, allocation size gets truncated which makes allocation succeed when it should     fail. (CVE-2017-9725)    - The ext4_iget function in fs/ext4/inode.c in the Linux kernel through 4.15.15 mishandles the case of a     root directory with a zero i_links_count, which allows attackers to cause a denial of service     (ext4_process_freed_data NULL pointer dereference and OOPS) via a crafted ext4 image. (CVE-2018-1092)    - drivers/input/serio/i8042.c in the Linux kernel before 4.12.4 allows attackers to cause a denial of     service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the     port->exists value can change after it is validated. (CVE-2017-18079)    - In the Linux kernel before 4.7, the amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the     pinctrl_unregister function, leading to a double free. (CVE-2017-18174)    - The __munlock_pagevec function in mm/mlock.c in the Linux kernel before 4.11.4 allows local users to cause     a denial of service (NR_MLOCK accounting corruption) via crafted use of mlockall and munlockall system     calls.
(CVE-2017-18221)    - The perf_cpu_time_max_percent_handler function in kernel/events/core.c in the Linux kernel before 4.11     allows local users to cause a denial of service (integer overflow) or possibly have unspecified other impact via a large value, as demonstrated by an incorrect sample-rate calculation. (CVE-2017-18255)    - ** DISPUTED ** Race condition in the store_int_with_restart() function in arch/x86/kernel/cpu/mcheck/mce.c     in the Linux kernel through 4.15.7 allows local users to cause a denial of service (panic) by leveraging     root access to write to the check_interval file in a /sys/devices/system/machinecheck/machinecheck directory. NOTE: a third party has indicated that this report is not security relevant.     (CVE-2018-7995)    - In the hidp_process_report in bluetooth, there is an integer overflow. This could lead to an out of bounds     write with no additional execution privileges needed. User interaction is not needed for exploitation.     Product: Android Versions: Android kernel Android ID: A-65853588 References: Upstream kernel.     (CVE-2018-9363)    - In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a     missing bounds check. This could lead to local escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation. Product: Android Versions:
Android kernel Android     ID: A-71361580. (CVE-2018-9516)  Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3848-2 advisory.

  - In the Linux kernel before 4.7, the amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the     pinctrl_unregister function, leading to a double free. (CVE-2017-18174)

  - An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-     timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval     and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This     basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and     siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer     overflow) via crafted mmap, futex, timer_create, and timer_settime system calls. (CVE-2018-12896)

  - In the Linux kernel before 4.17, a local attacker able to set attributes on an xfs filesystem could make     this filesystem non-operational until the next mount by triggering an unchecked error condition during an     xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandles     ATTR_REPLACE operations with conversion of an attr from short to long form. (CVE-2018-18690)

  - An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc     in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from     unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and     CVE-2018-16658. (CVE-2018-18710)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.120 to receive various security and bugfixes. The following security bugs were fixed :

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

  - CVE-2017-15951: The KEYS subsystem did not correctly     synchronize the actions of updating versus finding a key     in the 'negative' state to avoid a race condition, which     allowed local users to cause a denial of service or     possibly have unspecified other impact via crafted     system calls (bnc#1062840 bnc#1065615).

  - CVE-2017-16644: The hdpvr_probe function in     drivers/media/usb/hdpvr/hdpvr-core.c 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-2017-16912: The 'get_pipe()' function     (drivers/usb/usbip/stub_rx.c) 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     (drivers/usb/usbip/stub_rx.c) 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-2017-17975: Use-after-free in the usbtv_probe     function in drivers/media/usb/usbtv/usbtv-core.c allowed     attackers to cause a denial of service (system crash) or     possibly have unspecified other impact by triggering     failure of audio registration, because a kfree of the     usbtv data structure occurs during a usbtv_video_free     call, but the usbtv_video_fail label's code attempts to     both access and free this data structure (bnc#1074426).

  - CVE-2017-18174: The amd_gpio_remove function in     drivers/pinctrl/pinctrl-amd.c calls the     pinctrl_unregister function, leading to a double free     (bnc#1080533).

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

  - CVE-2018-1000026: A insufficient input validation     vulnerability in bnx2x network card driver could result     in DoS: Network card firmware assertion takes card     off-line. This attack appear to be exploitable via An     attacker on a must pass a very large, specially crafted     packet to the bnx2x card. This can be done from an     untrusted guest VM. (bnc#1079384).

  - CVE-2018-8087: Memory leak in the hwsim_new_radio_nl     function in drivers/net/wireless/mac80211_hwsim.c     allowed local users to cause a denial of service (memory     consumption) by triggering an out-of-array error case     (bnc#1085053).

  - CVE-2018-1068: Insufficient user provided offset     checking in the ebtables compat code allowed local     attackers to overwrite kernel memory and potentially     execute code. (bsc#1085107)

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