Summary

The Linux kernel before version 4.11 is vulnerable to a NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allows 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 is mishandled during session recovery.

    descriptionIt was discovered that the CIFS client implementation in the Linux kernel did not properly handle setup negotiation during session recovery, leading to a NULL pointer exception. An attacker could use this to create a malicious CIFS server that caused a denial of service (client system crash). (CVE-2018-1066) Jann Horn discovered that the procfs file system implementation in the Linux kernel did not properly restrict the ability to inspect the kernel stack of an arbitrary task. A local attacker could use this to expose sensitive information. (CVE-2018-17972) Jann Horn discovered that the mremap() system call in the Linux kernel did not properly flush the TLB when completing, potentially leaving access to a physical page after it has been released to the page allocator. A local attacker could use this to cause a denial of service (system crash), expose sensitive information, or possibly execute arbitrary code. (CVE-2018-18281) It was discovered that the socket implementation in the Linux kernel contained a type confusion error that could lead to memory corruption. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-9568). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu 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 :

  - Missing check in fs/inode.c:inode_init_owner() does not
    clear SGID bit on non-directories for
    non-members.(CVE-2018-13405)

  - A null pointer dereference in dccp_write_xmit()
    function in net/dccp/output.c in the Linux kernel
    allows a local user to cause a denial of service by a
    number of certain crafted system calls.(CVE-2018-1130)

  - A flaw was found in the Linux kernel, before 4.16.6
    where the cdrom_ioctl_media_changed function in
    drivers/cdrom/cdrom.c allows local attackers to use a
    incorrect bounds check in the CDROM driver
    CDROM_MEDIA_CHANGED ioctl to read out kernel
    memory.(CVE-2018-10940)

  - The madvise_willneed function in the Linux kernel
    allows local users to cause a denial of service
    (infinite loop) by triggering use of MADVISE_WILLNEED
    for a DAX mapping.(CVE-2017-18208)

  - fuse-backed file mmap-ed onto process cmdline arguments
    causes denial of service.(CVE-2018-1120)

  - Memory leak in the sas_smp_get_phy_events function in
    drivers/scsi/libsas/sas_expander.c in the Linux kernel
    allows local users to cause a denial of service (kernel
    memory exhaustion) via multiple read accesses to files
    in the /sys/class/sas_phy directory.(CVE-2018-7757)

  - A vulnerability was found in the Linux kernel's
    kernel/events/core.c:perf_cpu_time_max_percent_handler(
    ) function. Local privileged users could exploit this
    flaw to cause a denial of service due to integer
    overflow or possibly have unspecified other
    impact.(CVE-2017-18255)

  - A flaw was found in the Linux kernel in the way a local
    user could create keyrings for other users via keyctl
    commands. This may allow an attacker to set unwanted
    defaults, a denial of service, or possibly leak keyring
    information between users.(CVE-2017-18270)

  - The mm subsystem in the Linux kernel through 4.10.10
    does not properly enforce the CONFIG_STRICT_DEVMEM
    protection mechanism, which allows local users to read
    or write to kernel memory locations in the first
    megabyte (and bypass slab-allocation access
    restrictions) via an application that opens the
    /dev/mem file, related to arch/x86/mm/init.c and
    drivers/char/mem.c.(CVE-2017-7889)

  - The code in the drivers/scsi/libsas/sas_scsi_host.c
    file in the Linux kernel allow a physically proximate
    attacker to cause a memory leak in the ATA command
    queue and, thus, denial of service by triggering
    certain failure conditions.(CVE-2018-10021)

  - A flaw was found in the Linux kernel's client-side
    implementation of the cifs protocol. This flaw allows
    an attacker controlling the server to kernel panic a
    client which has the CIFS server
    mounted.(CVE-2018-1066)

  - A flaw was found in the alarm_timer_nsleep() function
    in kernel/time/alarmtimer.c in the Linux kernel. The
    ktime_add_safe() function is not used and an integer
    overflow can happen causing an alarm not to fire or
    possibly a denial-of-service if using a large relative
    timeout.(CVE-2018-13053)

  - An issue was discovered in the XFS filesystem in
    fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel. A
    NULL pointer dereference may occur for a corrupted xfs
    image after xfs_da_shrink_inode() is called with a NULL
    bp. This can lead to a system crash and a denial of
    service.(CVE-2018-13094)

  - A flaw was found in the Linux Kernel in the
    ucma_leave_multicast() function in
    drivers/infiniband/core/ucma.c which allows access to a
    certain data structure after freeing it in
    ucma_process_join(). This allows an attacker to cause a
    use-after-free bug and to induce kernel memory
    corruption, leading to a system crash or other
    unspecified impact. Due to the nature of the flaw,
    privilege escalation cannot be fully ruled out,
    although we believe it is unlikely.(CVE-2018-14734)

  - A race condition in the store_int_with_restart()
    function in arch/x86/kernel/cpu/mcheck/mce.c in the
    Linux kernel 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 (cpu
    number) directory.(CVE-2018-7995)

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

  - A flaw was found in the Linux kernel's client-side
    implementation of the cifs protocol. This flaw allows
    an attacker controlling the server to kernel panic a
    client which has the CIFS server
    mounted.(CVE-2018-1066)

  - Memory leak in the sas_smp_get_phy_events function in
    drivers/scsi/libsas/sas_expander.c in the Linux kernel
    allows local users to cause a denial of service (kernel
    memory exhaustion) via multiple read accesses to files
    in the /sys/class/sas_phy directory.(CVE-2018-7757)

  - A race condition in the store_int_with_restart()
    function in arch/x86/kernel/cpu/mcheck/mce.c in the
    Linux kernel 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 (cpu
    number) directory.(CVE-2018-7995)

  - Improper validation in the bnx2x network card driver of
    the Linux kernel version 4.15 can allow for denial of
    service (DoS) attacks via a packet with a gso_size
    larger than ~9700 bytes. Untrusted guest VMs can
    exploit this vulnerability in the host machine, causing
    a crash in the network card.(CVE-2018-1000026)

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.");

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2015-9016 Ming Lei reported a race condition in the multiqueue block layer (blk-mq). On a system with a driver using blk-mq (mtip32xx, null_blk, or virtio_blk), a local user might be able to use this for denial of service or possibly for privilege escalation. - CVE-2017-0861 Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice. - CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the

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

    descriptionAccording to the versions of the kernel packages installed, the EulerOS 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):Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache.(CVE-2017-5754)The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access.(CVE-2017-5897)The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows 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.(CVE-2017-7261)The KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls.(CVE-2017-7472)A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.(CVE-2017-7518)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)The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted xfs image.(CVE-2018-10323)The Linux kernel before version 4.11 is vulnerable to a NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allows 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 is mishandled during session recovery.(CVE-2018-1066)The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls.(CVE-2018-10675)An issue was discovered in fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel through 4.17.3. An OOPS may occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp.(CVE-2018-13094)An issue was discovered in fs/xfs/xfs_super.c in the Linux kernel before 4.18. A use after free exists, related to xfs_fs_fill_super failure.(CVE-2018-20976)Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.(CVE-2018-3693)In the function sbusfb_ioctl_helper() in drivers/video/fbdev/sbuslib.c in the Linux kernel through 4.15, an integer signedness error allows arbitrary information leakage for the FBIOPUTCMAP_SPARC and FBIOGETCMAP_SPARC commands.(CVE-2018-6412)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 nfc_llcp_build_sdreq_tlv of llcp_commands.c, there is a possible out of bounds write due to a missing bounds check.
