The KEYS subsystem in the Linux kernel through 4.13.7 mishandles use of add_key for a key that already exists but is uninstantiated, which allows 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.

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 acpi_smbus_hc_add function in drivers/acpi/sbshc.c     in the Linux kernel through 4.14.15 allows local users     to obtain sensitive address information by reading     dmesg data from an SBS HC printk call.(CVE-2018-5750i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. A use-after-free is possible in     try_merge_free_space() when mounting a crafted btrfs     image due to a lack of chunk type flag checks in     btrfs_check_chunk_valid() in the fs/btrfs/volumes.c     function. This could lead to a denial of service or     other unspecified impact.(CVE-2018-14611i1/4%0

  - A flaw was found in the way the Linux kernel visor     driver handles certain invalid USB device descriptors.
    The driver assumes that the device always has at least     one bulk OUT endpoint. By using a specially crafted USB     device (without a bulk OUT endpoint), an unprivileged     user with physical access could trigger a kernel     NULL-pointer dereference and cause a system panic     (denial of service).(CVE-2015-7566i1/4%0

  - It was found that the RFC 5961 challenge ACK rate     limiting as implemented in the Linux kernel's     networking subsystem allowed an off-path attacker to     leak certain information about a given connection by     creating congestion on the global challenge ACK rate     limit counter and then measuring the changes by probing     packets. An off-path attacker could use this flaw to     either terminate TCP connection and/or inject payload     into non-secured TCP connection between two endpoints     on the network.(CVE-2016-5696i1/4%0

  - It was found that the Bluebooth Network Encapsulation     Protocol (BNEP) implementation did not validate the     type of second socket passed to the BNEPCONNADD     ioctl(), which could lead to memory corruption. A local     user with the CAP_NET_ADMIN capability can use this for     denial of service (crash or data corruption) or     possibly for privilege escalation. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we feel it is unlikely.(CVE-2017-15868i1/4%0

  - A vulnerability was found in the key management     subsystem of the Linux kernel. An update on an     uninstantiated key could cause a kernel panic, leading     to denial of service (DoS).(CVE-2017-15299i1/4%0

  - The rfcomm_sock_bind function in     net/bluetooth/rfcomm/sock.c in the Linux kernel before     4.2 allows local users to obtain sensitive information     or cause a denial of service (NULL pointer dereference)     via vectors involving a bind system call on a Bluetooth     RFCOMM socket.(CVE-2015-8956i1/4%0

  - arch/mips/include/asm/thread_info.h in the Linux kernel     before 3.14.8 on the MIPS platform does not configure
    _TIF_SECCOMP checks on the fast system-call path, which     allows local users to bypass intended PR_SET_SECCOMP     restrictions by executing a crafted application without     invoking a trace or audit subsystem.(CVE-2014-4157i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem     code. A stack-out-of-bounds write in     ext4_update_inline_data() is possible when mounting and     writing to a crafted ext4 image. An attacker could use     this to cause a system crash and a denial of     service.(CVE-2018-10880i1/4%0

  - The aac_send_raw_srb function in     drivers/scsi/aacraid/commctrl.c in the Linux kernel     through 3.12.1 does not properly validate a certain     size value, which allows local users to cause a denial     of service (invalid pointer dereference) or possibly     have unspecified other impact via an     FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted     SRB command.(CVE-2013-6380i1/4%0

  - 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-2016-9588i1/4%0

  - 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 if     using a large relative timeout.(CVE-2018-13053i1/4%0

  - net/llc/sysctl_net_llc.c in the Linux kernel before     3.19 uses an incorrect data type in a sysctl table,     which allows local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry.(CVE-2015-2041i1/4%0

  - Incorrect error handling in the set_mempolicy() and     mbind() compat syscalls in 'mm/mempolicy.c' in the     Linux kernel allows local users to obtain sensitive     information from uninitialized stack data by triggering     failure of a certain bitmap operation.(CVE-2017-7616i1/4%0

  - The snd_msnd_interrupt function in     sound/isa/msnd/msnd_pinnacle.c in the Linux kernel     through 4.11.7 allows local users to cause a denial of     service (over-boundary access) or possibly have     unspecified other impact by changing the value of a     message queue head pointer between two kernel reads of     that value, aka a 'double fetch'     vulnerability.(CVE-2017-9984i1/4%0

  - An integer overflow was discovered in the     qla2x00_sysfs_write_optrom_ctl function in     drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel     through 4.12.10. This flaw allows local users to cause     a denial of service (memory corruption and system     crash) by leveraging root access.(CVE-2017-14051i1/4%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-2014-4654i1/4%0

  - An information leak flaw was found in the way the Linux     kernel's Virtual Dynamic Shared Object (vDSO)     implementation performed address randomization. A     local, unprivileged user could use this flaw to leak     kernel memory addresses to user-space.(CVE-2014-9585i1/4%0

  - The usbhid_parse function in     drivers/hid/usbhid/hid-core.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (out-of-bounds read and system crash) or     possibly have unspecified other impact via a crafted     USB device.(CVE-2017-16533i1/4%0

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This     can result in a kernel panic causing a local denial of     service.(CVE-2017-14106i1/4%0

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.

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

  - It was found that in the Linux kernel through     v4.14-rc5, bio_map_user_iov() and bio_unmap_user() in     'block/bio.c' do unbalanced pages refcounting if IO     vector has small consecutive buffers belonging to the     same page. bio_add_pc_page() merges them into one, but     the page reference is never dropped, causing a memory     leak and possible system lockup due to out-of-memory     condition.(CVE-2017-12190)

  - A vulnerability was found in the Key Management sub     component of the Linux kernel, where when trying to     issue a KEYTCL_READ on a negative key would lead to a     NULL pointer dereference. A local attacker could use     this flaw to crash the kernel.(CVE-2017-12192)

  - A flaw was found in the Linux kernel's implementation     of associative arrays introduced in 3.13. This     functionality was backported to the 3.10 kernels in Red     Hat Enterprise Linux 7. The flaw involved a null     pointer dereference in assoc_array_apply_edit() due to     incorrect node-splitting in assoc_array implementation.
    This affects the keyring key type and thus key addition     and link creation operations may cause the kernel to     panic.(CVE-2017-12193)

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This     can result in a kernel panic causing a local denial of     service.(CVE-2017-14106)

  - The move_pages system call in mm/migrate.c in the Linux     kernel doesn't check the effective uid of the target     process. This enables a local attacker to learn the     memory layout of a setuid executable allowing     mitigation of ASLR.(CVE-2017-14140)

  - The iscsi_if_rx() function in     'drivers/scsi/scsi_transport_iscsi.c' in the Linux     kernel from v2.6.24-rc1 through 4.13.2 allows local     users to cause a denial of service (a system panic) by     making a number of certain syscalls by leveraging     incorrect length validation in the kernel     code.(CVE-2017-14489)

  - The sg_ioctl() function in 'drivers/scsi/sg.c' in the     Linux kernel, from version 4.12-rc1 to 4.14-rc2, allows     local users to obtain sensitive information from     uninitialized kernel heap-memory locations via an     SG_GET_REQUEST_TABLE ioctl call for     '/dev/sg0'.(CVE-2017-14991)

  - The tower_probe function in     drivers/usb/misc/legousbtower.c in the Linux kernel     before 4.8.1 allows local users (who are physically     proximate for inserting a crafted USB device) to gain     privileges by leveraging a write-what-where condition     that occurs after a race condition and a NULL pointer     dereference.(CVE-2017-15102)

  - A vulnerability was found in the Linux kernel when     peeling off an association to the socket in another     network namespace. All transports in this association     are not to be rehashed and keep using the old key in     hashtable, thus removing transports from hashtable when     closing the socket, all transports are being freed.
    Later on a use-after-free issue could be caused when     looking up an association and dereferencing the     transports.(CVE-2017-15115)

  - 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 use-after-free vulnerability was found when issuing     an ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption     or possibly privilege escalation.(CVE-2017-15265)

  - A flaw was found in the implementation of associative     arrays where the add_key systemcall and KEYCTL_UPDATE     operations allowed for a NULL payload with a nonzero     length. When accessing the payload within this length     parameters value, an unprivileged user could trivially     cause a NULL pointer dereference (kernel     oops).(CVE-2017-15274)

  - A vulnerability was found in the key management     subsystem of the Linux kernel. An update on an     uninstantiated key could cause a kernel panic, leading     to denial of service (DoS).(CVE-2017-15299)

  - It was found that fanout_add() in     'net/packet/af_packet.c' in the Linux kernel, before     version 4.13.6, allows local users to gain privileges     via crafted system calls that trigger mishandling of     packet_fanout data structures, because of a race     condition (involving fanout_add and packet_do_bind)     that leads to a use-after-free bug.(CVE-2017-15649)

  - The usb_serial_console_disconnect function in     drivers/usb/serial/console.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (use-after-free and system crash) or possibly     have unspecified other impact via a crafted USB device,     related to disconnection and failed     setup.(CVE-2017-16525)

  - The drivers/uwb/uwbd.c in the Linux kernel, before     4.13.6, allows local users to cause a denial of service     (general protection fault and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16526)

  - The sound/usb/mixer.c in the Linux kernel, before     4.13.8, allows local users to cause a denial of service     (snd_usb_mixer_interrupt use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16527)

  - The sound/core/seq_device.c in the Linux kernel, before     4.13.4, allows local users to cause a denial of service     (snd_rawmidi_dev_seq_free use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16528)

  - The snd_usb_create_streams function in sound/usb/card.c     in the Linux kernel, before 4.13.6, allows local users     to cause a denial of service (out-of-bounds read and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16529)

  - The uas driver in the Linux kernel before 4.13.6 allows     local users to cause a denial of service (out-of-bounds     read and system crash), or possibly have unspecified     other impacts via a crafted USB device, related to     drivers/usb/storage/uas-detect.h and     drivers/usb/storage/uas.c.(CVE-2017-16530)

  - The function drivers/usb/core/config.c in the Linux     kernel, allows local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB device,     related to the USB_DT_INTERFACE_ASSOCIATION     descriptor.(CVE-2017-16531)

  - The get_endpoints function in     drivers/usb/misc/usbtest.c in the Linux kernel through     4.13.11 allows local users to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16532)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:0654 advisory.

    The kernel-alt packages provide the Linux kernel version 4.x.

    The following packages have been upgraded to a later upstream version: kernel-alt (4.14.0). (BZ#1492717)

    Security Fix(es):

    * 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). As a result, an unprivileged attacker could use     this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted     cache side-channel attacks. (CVE-2017-5715, Important, ARM)

    Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. 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). As a result, an unprivileged attacker could use this     flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel     attacks. (CVE-2017-5753, Important, ARM)

    Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution     of instruction permission faults, exception generation triggered by a faulting access is suppressed until     the retirement of the whole instruction block. In a combination with the fact that memory accesses may     populate the cache even when the block is being dropped and never committed (executed), an unprivileged     local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache     side-channel attacks. (CVE-2017-5754, Important, ARM)

    * kernel: memory leak when merging buffers in SCSI IO vectors (CVE-2017-12190, Moderate)

    * kernel: net: double-free and memory corruption in get_net_ns_by_id() (CVE-2017-15129, Moderate)

    * kernel: Incorrect updates of uninstantiated keys crash the kernel (CVE-2017-15299, Moderate)

    * kernel: Missing capabilities check in net/netfilter/nfnetlink_cthelper.c allows for unprivileged access     to systemwide nfnl_cthelper_list structure (CVE-2017-17448, Moderate)

    * kernel: Missing namespace check in net/netlink/af_netlink.c allows for network monitors to observe     systemwide activity (CVE-2017-17449, Moderate)

    * kernel: Arbitrary stack overwrite causing oops via crafted signal frame (CVE-2017-1000255, Moderate)

    * kernel: Stack information leak in the EFS element (CVE-2017-1000410, Moderate)

    * kernel: Race condition in sound system can lead to denial of service (CVE-2018-1000004, Moderate)

    * kernel: Buffer overflow in mp_override_legacy_irq() (CVE-2017-11473, Low)

    * kernel: Integer overflow in futex.c:futux_requeue can lead to denial of service or unspecified impact     (CVE-2018-6927, Low)

The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-1068: Fixed flaw in the implementation of     32-bit syscall interface for bridging. 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 'stub_send_ret_submit()' function     allowed attackers to cause a denial of service (NULL     pointer dereference) via a specially crafted USB over IP     packet (bnc#1078669).

  - CVE-2016-7915: The hid_input_field function allowed     physically proximate attackers to obtain sensitive     information from kernel memory or cause a denial of     service (out-of-bounds read) by connecting a device     (bnc#1010470).

  - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user     functions did unbalanced refcounting when a SCSI I/O     vector had small consecutive buffers belonging to the     same page. The bio_add_pc_page function merged them into     one, but the page reference was never dropped. This     caused a memory leak and possible system lockup     (exploitable against the host OS by a guest OS user, if     a SCSI disk is passed through to a virtual machine) due     to an out-of-memory condition (bnc#1062568).

  - CVE-2017-16912: The 'get_pipe()' function allowed     attackers to cause a denial of service (out-of-bounds     read) via a specially crafted USB over IP packet     (bnc#1078673).

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

CVE-2016-10208

Sergej Schumilo and Ralf Spenneberg discovered that a crafted ext4 filesystem could trigger memory corruption when it is mounted. A user that can provide a device or filesystem image to be mounted could use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-8824

Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for 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

CVE-2017-8831

Pengfei Wang discovered that the saa7164 video capture driver re-reads data from a PCI device after validating it. A physically present user able to attach a specially designed PCI device could use this for privilege escalation.

CVE-2017-12190

Vitaly Mayatskikh discovered that the block layer did not correctly count page references for raw I/O from user-space. This can be exploited by a guest VM with access to a host SCSI device for denial of service (memory exhaustion) or potentially for privilege escalation.

CVE-2017-13080

A vulnerability was found in the WPA2 protocol that could lead to reinstallation of the same Group Temporal Key (GTK), which substantially reduces the security of wifi encryption. This is one of the issues collectively known as 'KRACK'.

Updates to GTKs are usually handled by the wpa package, where this issue was already fixed (DLA-1150-1). However, some wifi devices can remain active and update GTKs autonomously while the system is suspended. The kernel must also check for and ignore key reinstallation.

CVE-2017-14051

'shqking' reported that the qla2xxx SCSI host driver did not correctly validate I/O to the 'optrom' sysfs attribute of the devices it creates. This is unlikely to have any security impact.

CVE-2017-15115

Vladis Dronov reported that the SCTP implementation did not correctly handle 'peel-off' of an association to another net namespace. This leads to a use-after-free, which a local user can exploit for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the sctp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-sctp.conf install sctp false

CVE-2017-15265

Michael23 Yu reported a race condition in the ALSA sequencer subsystem involving creation and deletion of ports, which could lead to a use-after-free. A local user with access to an ALSA sequencer device can use this for denial of service (crash or data loss) or possibly for privilege escalation.

CVE-2017-15299

Eric Biggers discovered that the KEYS subsystem did not correctly handle update of an uninstantiated key, leading to a null dereference.
A local user can use this for denial of service (crash).

CVE-2017-15649

'nixioaming' reported a race condition in the packet socket (AF_PACKET) implementation involving rebinding to a fanout group, which could lead to a use-after-free. A local user with the CAP_NET_RAW capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-15868

Al Viro found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of the second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16525

Andrey Konovalov reported that the USB serial console implementation did not correctly handle disconnection of unusual serial devices, leading to a use-after-free. A similar issue was found in the case where setup of a serial console fails. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16527

Andrey Konovalov reported that the USB sound mixer driver did not correctly cancel I/O in case it failed to probe a device, which could lead to a use-after-free. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16529

Andrey Konovalov reported that the USB sound driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16531

Andrey Konovalov reported that the USB core did not validate IAD lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16532

Andrey Konovalov reported that the USB test driver did not correctly handle devices with specific combinations of endpoints. A physically present user with a specially designed USB device can use this to cause a denial of service (crash).

CVE-2017-16533

Andrey Konovalov reported that the USB HID driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16535

Andrey Konovalov reported that the USB core did not validate BOS descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16536

Andrey Konovalov reported that the cx231xx video capture driver did not fully validate the device endpoint configuration, which could lead to a null dereference. A physically present user with a specially designed USB device can use this to cause a denial of service (crash).

CVE-2017-16537

Andrey Konovalov reported that the imon RC driver did not fully validate the device interface configuration, which could lead to a null dereference. A physically present user with a specially designed USB device can use this to cause a denial of service (crash).

CVE-2017-16643

Andrey Konovalov reported that the gtco tablet driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16649

Bj&oslash;rn Mork found that the cdc_ether network driver did not validate the device's maximum segment size, potentially leading to a division by zero. A physically present user with a specially designed USB device can use this to cause a denial of service (crash).

CVE-2017-16939

Mohamed Ghannam reported (through Beyond Security's SecuriTeam Secure Disclosure program) that the IPsec (xfrm) implementation did not correctly handle some failure cases when dumping policy information through netlink. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-1000407

Andrew Honig reported that the KVM implementation for Intel processors allowed direct access to host I/O port 0x80, which is not generally safe. On some systems this allows a guest VM to cause a denial of service (crash) of the host.

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.96-2. This version also includes bug fixes from upstream versions up to and including 3.2.96. It also fixes some regressions caused by the fix for CVE-2017-1000364, which was included in DLA-993-1.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Incorrect updates of uninstantiated keys crash the kernel

A vulnerability was found in the key management subsystem of the Linux kernel. An update on an uninstantiated key could cause a kernel panic, leading to denial of service (DoS). (CVE-2017-15299)

Memory leak when merging buffers in SCSI IO vectors

It was found that in the Linux kernel through v4.14-rc5, bio_map_user_iov() and bio_unmap_user() in 'block/bio.c' do unbalanced pages refcounting if IO vector has small consecutive buffers belonging to the same page. bio_add_pc_page() merges them into one, but the page reference is never dropped, causing a memory leak and possible system lockup due to out-of-memory condition. (CVE-2017-12190)

NULL pointer dereference due to incorrect node-splitting in assoc_array implementation

A flaw was found in the Linux kernel's implementation of associative arrays introduced in 3.13. This functionality was backported to the 3.10 kernels in Red Hat Enterprise Linux 7. The flaw involved a NULL pointer dereference in assoc_array_apply_edit() due to incorrect node-splitting in assoc_array implementation. This affects the keyring key type and thus key addition and link creation operations may cause the kernel to panic. (CVE-2017-12193)

Arbitrary stack overwrite causing oops via crafted signal frame

A flaw was found in the Linux kernel's handling of signal frame on PowerPC systems. A malicious local user process could craft a signal frame allowing an attacker to corrupt memory. (CVE-2017-1000255)

Race condition in the KEYS subsystem

The KEYS subsystem in the Linux kernel before 4.13.10 does not correctly synchronize the actions of updating versus finding a key in the 'negative' state to avoid a race condition, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls. (CVE-2017-15951)

The 4.13.8 update contains a number of important fixes across the tree.
