    "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.
    
    CVE-2016-7911
    
    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.

    descriptionThe SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.69 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501). - CVE-2015-8963: Race condition in kernel/events/core.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by leveraging incorrect handling of an swevent data structure during a CPU unplug operation (bnc#1010502). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716). - CVE-2016-7911: Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call (bnc#1010711). - CVE-2016-7913: The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed 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 (bnc#1010478). - CVE-2016-7914: The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel did not check whether a slot is a leaf, which allowed 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, as demonstrated by the keyutils test suite (bnc#1010475). - CVE-2016-8399: An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID: A-31349935 (bnc#1014746). - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel, in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833). - CVE-2016-8645: The TCP stack in the Linux kernel mishandled skb truncation, which allowed local users to cause a denial of service (system crash) via a crafted application that made sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (bnc#1009969). - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux kernel allowed local users to bypass integer overflow checks, and cause a denial of service (memory corruption) or have unspecified other impact, by leveraging access to a vfio PCI device file for a VFIO_DEVICE_SET_IRQS ioctl call, aka a

      - CVE-2015-8964: The tty_set_termios_ldisc function in
        drivers/tty/tty_ldisc.c in the Linux kernel allowed
        local users to obtain sensitive information from kernel
        memory by reading a tty data structure (bnc#1010507).
    
      - CVE-2016-10088: The sg implementation in the Linux
        kernel did not properly restrict write operations in
        situations where the KERNEL_DS option is set, which
        allowed local users to read or write to arbitrary kernel

        (use-after-free) by leveraging access to a /dev/sg
        device, related to block/bsg.c and drivers/scsi/sg.c.
        NOTE: this vulnerability exists because of an incomplete
        fix for CVE-2016-9576 (bnc#1017710).
    
      - CVE-2016-7910: Use-after-free vulnerability in the
        disk_seqf_stop function in block/genhd.c in the Linux
        kernel allowed local users to gain privileges by

        mishandled skb truncation, which allowed local users to
        cause a denial of service (system crash) via a crafted
        application that made sendto system calls, related to
        net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c
        (bnc#1009969).
    
      - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux
        kernel allowed local users to bypass integer overflow
        checks, and cause a denial of service (memory

        confusion bug' (bnc#1007197).
    
      - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the
        Linux kernel misuses the kzalloc function, which allowed
        local users to cause a denial of service (integer
        overflow) or have unspecified other impact by leveraging
        access to a vfio PCI device file (bnc#1007197).
    
      - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux
        kernel did not properly initialize Code Segment (CS) in
        certain error cases, which allowed local users to obtain
        sensitive information from kernel stack memory via a
        crafted application (bnc#1013038).
    
      - CVE-2016-9793: The sock_setsockopt function in
        net/core/sock.c in the Linux kernel mishandled negative
        values of sk_sndbuf and sk_rcvbuf, which allowed local
        users to cause a denial of service (memory corruption
        and system crash) or possibly have unspecified other
        impact by leveraging the CAP_NET_ADMIN capability for a
        crafted setsockopt system call with the (1)
        SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531
        1013542).
    
      - CVE-2016-9806: Race condition in the netlink_dump
        function in net/netlink/af_netlink.c in the Linux kernel
        allowed local users to cause a denial of service (double
        free) or possibly have unspecified other impact via a
        crafted application that made sendmsg system calls,
        leading to a free operation associated with a new dump
        that started earlier than anticipated (bnc#1013540
        1017589).
    
      - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux
        kernel allowed 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 (bsc#1019851).
    
      - CVE-2017-2583: Fixed broken emulation of 'MOV SS, null
        selector' (bsc#1020602).
    
      - CVE-2017-5551: Clear SGID bit when setting file
        permissions on tmpfs (bsc#1021258).

  • NASL familyHuawei Local Security Checks
    NASL idEULEROS_SA-2019-1489.NASL
    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - An information-leak vulnerability was found in the kernel when it truncated a file to a smaller size which consisted of an inline extent that was compressed. The data between the new file size and the old file size was not discarded and the number of bytes used by the inode were not correctly decremented, which gave the wrong report for callers of the stat(2) syscall. This wasted metadata space and allowed for the truncated data to be leaked, and data corruption or loss to occur. A caller of the clone ioctl could exploit this flaw by using only standard file-system operations without root access to read the truncated data.(CVE-2015-8374) - A flaw was found in the Linux kernel
