A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-09331 advisory.

  - The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through 4.8.11 does not ensure that memory     is allocated for limb data, which allows local users to cause a denial of service (stack memory corruption     and panic) via an add_key system call for an RSA key with a zero exponent. (CVE-2016-8650)

  - The sock_setsockopt function in net/core/sock.c in the Linux kernel before 4.8.14 mishandles negative     values of sk_sndbuf and sk_rcvbuf, which allows 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.
    (CVE-2016-9793)

  - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain     privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)

  - A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files     before 4.9.10. An empty (null) write to this file can crash the system by causing the system to attempt to     access unmapped kernel memory. (CVE-2017-2618)

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 :

  - drivers/soc/qcom/qdsp6v2/voice_svc.c in the QDSP6v2     Voice Service driver for the Linux kernel 3.x, as used     in Qualcomm Innovation Center (QuIC) Android     contributions for MSM devices and other products,     allows attackers to cause a denial of service (memory     corruption) or possibly have unspecified other impact     via a write request, as demonstrated by a     voice_svc_send_req buffer overflow.(CVE-2016-5343i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's Advanced Linux Sound Architecture (ALSA)     implementation handled user controls. A local,     privileged user could use this flaw to crash the     system.(CVE-2014-4655i1/4%0

  - Race condition in the handle_to_path function in     fs/fhandle.c in the Linux kernel through 3.19.1 allows     local users to bypass intended size restrictions and     trigger read operations on additional memory locations     by changing the handle_bytes value of a file handle     during the execution of this function.(CVE-2015-1420i1/4%0

  - A flaw was found in the way the Linux kernel's keys     subsystem handled the termination condition in the     associative array garbage collection functionality. A     local, unprivileged user could use this flaw to crash     the system.(CVE-2014-3631i1/4%0

  - A flaw was found in the ext4 subsystem. This     vulnerability is a use after free vulnerability was     found in __ext4_journal_stop(). Attackers could abuse     this to allow any code which attempts to deal with the     journal failure to be mishandled or not fail at all.
    This could lead to data corruption or     crashes.(CVE-2015-8961i1/4%0

  - Buffer overflow in the oz_cdev_write function in     drivers/staging/ozwpan/ozcdev.c in the Linux kernel     before 3.12 allows local users to cause a denial of     service or possibly have unspecified other impact via a     crafted write operation.(CVE-2013-4513i1/4%0

  - The nfnetlink_rcv_batch() function in     'net/netfilter/nfnetlink.c' in the Linux kernel before     4.5 does not check whether a batch message's length     field is large enough, which allows local users to     obtain sensitive information from kernel memory or     cause a denial of service (infinite loop or     out-of-bounds read) by leveraging the CAP_NET_ADMIN     capability.(CVE-2016-7917i1/4%0

  - Array index error in the kvm_vm_ioctl_create_vcpu     function in virt/kvm/kvm_main.c in the KVM subsystem in     the Linux kernel through 3.12.5 allows local users to     gain privileges via a large id value.(CVE-2013-4587i1/4%0

  - A leak of information was possible when issuing a     netlink command of the stack memory area leading up to     this function call. An attacker could use this to     determine stack information for use in a later     exploit.(CVE-2016-5243i1/4%0

  - An issue was discovered in the Linux kernel in the F2FS     filesystem code. A NULL pointer dereference in     fscrypt_do_page_crypto() in the fs/crypto/crypto.c     function can occur when operating on a file on a     corrupted f2fs image.(CVE-2018-14616i1/4%0

  - An out-of-bounds flaw was found in the kernel, where     the sco_sock_bind() function (bluetooth/sco) did not     check the length of its sockaddr parameter. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8575i1/4%0

  - A denial of service vulnerability was found in the     WhiteHEAT USB Serial Driver (whiteheat_attach function     in drivers/usb/serial/whiteheat.c). In the driver, the     COMMAND_PORT variable was hard coded and set to 4 (5th     element). The driver assumed that the number of ports     would always be 5 and used port number 5 as the command     port. However, when using a USB device in which the     number of ports was set to a number less than 5 (for     example, 3), the driver triggered a kernel NULL-pointer     dereference. A non-privileged attacker could use this     flaw to panic the host.(CVE-2015-5257i1/4%0

  - The LLC subsystem in the Linux kernel does not ensure     that a certain destructor exists in required     circumstances, which allows local users to cause a     denial of service (BUG_ON) or possibly have unspecified     other impact via crafted system calls.(CVE-2017-6345i1/4%0

  - A vulnerability was found in Linux kernel. There is an     information leak in file sound/core/timer.c of the     latest mainline Linux kernel. The stack object aEURoer1aEUR     has a total size of 32 bytes. Its field aEURoeeventaEUR and     aEURoevalaEUR both contain 4 bytes padding. These 8 bytes     padding bytes are sent to user without being     initialized.(CVE-2016-4578i1/4%0

  - An information leak flaw was found in the way the Linux     kernel changed certain segment registers and     thread-local storage (TLS) during a context switch. A     local, unprivileged user could use this flaw to leak     the user space TLS base address of an arbitrary     process.(CVE-2014-9419i1/4%0

  - A flaw was found in the way memory was being allocated     on the stack for user space binaries. If heap (or     different memory region) and stack memory regions were     adjacent to each other, an attacker could use this flaw     to jump over the stack guard gap, cause controlled     memory corruption on process stack or the adjacent     memory region, and thus increase their privileges on     the system. This is a kernel-side mitigation which     increases the stack guard gap size from one page to 1     MiB to make successful exploitation of this issue more     difficult.(CVE-2017-1000364i1/4%0

  - A flaw was found in the Linux kernel's handling of     clearing SELinux attributes on /proc/pid/attr files. An     empty (null) write to this file can crash the system by     causing the system to attempt to access unmapped kernel     memory.(CVE-2017-2618i1/4%0

  - A use-after-free vulnerability was found in ALSA pcm     layer, which allows local users to cause a denial of     service, memory corruption, or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9794i1/4%0

  - A flaw was found in the way the Linux kernel's floppy     driver handled user space provided data in certain     error code paths while processing FDRAWCMD IOCTL     commands. A local user with write access to /dev/fdX     could use this flaw to free (using the kfree()     function) arbitrary kernel memory. (CVE-2014-1737,     Important)t was found that the Linux kernel's floppy     driver leaked internal kernel memory addresses to user     space during the processing of the FDRAWCMD IOCTL     command. A local user with write access to /dev/fdX     could use this flaw to obtain information about the     kernel heap arrangement. (CVE-2014-1738, Low)Note: A     local user with write access to /dev/fdX could use     these two flaws (CVE-2014-1737 in combination with     CVE-2014-1738) to escalate their privileges on the     system.(CVE-2014-1737i1/4%0

  - An out-of-bounds memory access flaw was found in the     Linux kernel's aiptek USB tablet driver (aiptek_probe()     function in drivers/input/tablet/aiptek.c). The driver     assumed that the interface always had at least one     endpoint. By using a specially crafted USB device with     no endpoints on one of its interfaces, an unprivileged     user with physical access to the system could trigger a     kernel NULL pointer dereference, causing the system to     panic.(CVE-2015-7515i1/4%0

Security Fix(es) :

* A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system.
(CVE-2017-2636, Important)

* 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, Moderate)

* A flaw was found in the Linux kernel's implementation of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt() system call. Users with non-namespace CAP_NET_ADMIN are able to trigger this call and create a situation in which the sockets sendbuff data size could be negative.

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

  - CVE-2016-6786 / CVE-2016-6787     It was discovered that the performance events subsystem     does not properly manage locks during certain     migrations, allowing a local attacker to escalate     privileges. This can be mitigated by disabling     unprivileged use of performance events:sysctl     kernel.perf_event_paranoid=3

  - CVE-2016-8405     Peter Pi of Trend Micro discovered that the frame buffer     video subsystem does not properly check bounds while     copying color maps to userspace, causing a heap buffer     out-of-bounds read, leading to information disclosure.

  - CVE-2016-9191     CAI Qian discovered that reference counting is not     properly handled within proc_sys_readdir in the sysctl     implementation, allowing a local denial of service     (system hang) or possibly privilege escalation.

  - CVE-2017-2583     Xiaohan Zhang reported that KVM for amd64 does not     correctly emulate loading of a null stack selector. This     can be used by a user in a guest VM for denial of     service (on an Intel CPU) or to escalate privileges     within the VM (on an AMD CPU).

  - CVE-2017-2584     Dmitry Vyukov reported that KVM for x86 does not     correctly emulate memory access by the SGDT and SIDT     instructions, which can result in a use-after-free and     information leak.

  - CVE-2017-2596     Dmitry Vyukov reported that KVM leaks page references     when emulating a VMON for a nested hypervisor. This can     be used by a privileged user in a guest VM for denial of     service or possibly to gain privileges in the host.

  - CVE-2017-2618     It was discovered that an off-by-one in the handling of     SELinux attributes in /proc/pid/attr could result in     local denial of service.

  - CVE-2017-5549     It was discovered that the KLSI KL5KUSB105 serial USB     device driver could log the contents of uninitialised     kernel memory, resulting in an information leak.

  - CVE-2017-5551     Jan Kara found that changing the POSIX ACL of a file on     tmpfs 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-2017-5897     Andrey Konovalov discovered an out-of-bounds read flaw     in the ip6gre_err function in the IPv6 networking code.

  - CVE-2017-5970     Andrey Konovalov discovered a denial-of-service flaw in     the IPv4 networking code. This can be triggered by a     local or remote attacker if a local UDP or raw socket     has the IP_RETOPTS option enabled.

  - CVE-2017-6001     Di Shen discovered a race condition between concurrent     calls to the performance events subsystem, allowing a     local attacker to escalate privileges. This flaw exists     because of an incomplete fix of CVE-2016-6786. This can     be mitigated by disabling unprivileged use of     performance events: sysctl kernel.perf_event_paranoid=3

  - CVE-2017-6074     Andrey Konovalov discovered a use-after-free     vulnerability in the DCCP networking code, which could     result in denial of service or local privilege     escalation. On systems that do not already have the dccp     module loaded, this can be mitigated by disabling     it:echo >> /etc/modprobe.d/disable-dccp.conf install     dccp false
