The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.90 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2017-1000252: The KVM subsystem in the Linux kernel     allowed guest OS users to cause a denial of service     (assertion failure, and hypervisor hang or crash) via an     out-of bounds guest_irq value, related to     arch/x86/kvm/vmx.c and virt/kvm/eventfd.c (bnc#1058038).

  - CVE-2017-10810: Memory leak in the     virtio_gpu_object_create function in     drivers/gpu/drm/virtio/virtgpu_object.c in the Linux     kernel allowed attackers to cause a denial of service     (memory consumption) by triggering object-initialization     failures (bnc#1047277).

  - CVE-2017-11472: The acpi_ns_terminate() function in     drivers/acpi/acpica/nsutils.c in the Linux kernel did     not flush the operand cache and causes a kernel stack     dump, which allowed local users to obtain sensitive     information from kernel memory and bypass the KASLR     protection mechanism (in the kernel through 4.9) via a     crafted ACPI table (bnc#1049580).

  - CVE-2017-11473: Buffer overflow in the     mp_override_legacy_irq() function in     arch/x86/kernel/acpi/boot.c in the Linux kernel allowed     local users to gain privileges via a crafted ACPI table     (bnc#1049603).

  - CVE-2017-12134: The xen_biovec_phys_mergeable function     in drivers/xen/biomerge.c in Xen might allow local OS     guest users to corrupt block device data streams and     consequently obtain sensitive memory information, cause     a denial of service, or gain host OS privileges by     leveraging incorrect block IO merge-ability calculation     (bnc#1051790 bnc#1053919).

  - CVE-2017-12153: A security flaw was discovered in the     nl80211_set_rekey_data() function in     net/wireless/nl80211.c in the Linux kernel This function     did not check whether the required attributes are     present in a Netlink request. This request can be issued     by a user with the CAP_NET_ADMIN capability and may     result in a NULL pointer dereference and system crash     (bnc#1058410).

  - CVE-2017-12154: The prepare_vmcs02 function in     arch/x86/kvm/vmx.c in the Linux kernel did not ensure     that the 'CR8-load exiting' and 'CR8-store exiting' L0     vmcs02 controls exist in cases where L1 omits the 'use     TPR shadow' vmcs12 control, which allowed KVM L2 guest     OS users to obtain read and write access to the hardware     CR8 register (bnc#1058507).

  - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2)     allowed reinstallation of the Group Temporal Key (GTK)     during the group key handshake, allowing an attacker     within radio range to replay frames from access points     to clients (bnc#1063667).

  - CVE-2017-14051: An integer overflow in the     qla2x00_sysfs_write_optrom_ctl function in     drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel     allowed local users to cause a denial of service (memory     corruption and system crash) by leveraging root access     (bnc#1056588).

  - CVE-2017-14106: The tcp_disconnect function in     net/ipv4/tcp.c in the Linux kernel allowed local users     to cause a denial of service (__tcp_select_window     divide-by-zero error and system crash) by triggering a     disconnect within a certain tcp_recvmsg code path     (bnc#1056982).

  - CVE-2017-14489: The iscsi_if_rx function in     drivers/scsi/scsi_transport_iscsi.c in the Linux kernel     allowed local users to cause a denial of service (panic)     by leveraging incorrect length validation (bnc#1059051).

  - CVE-2017-15649: net/packet/af_packet.c in the Linux     kernel allowed 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, a different vulnerability     than CVE-2017-6346 (bnc#1064388).

  - CVE-2017-7518: The Linux kernel was vulnerable to an     incorrect debug exception(#DB) error. It could occur     while emulating a syscall instruction and potentially     lead to guest privilege escalation. (bsc#1045922).

  - CVE-2017-7541: The brcmf_cfg80211_mgmt_tx function in     drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021     1.c in the Linux kernel allowed local users to cause a     denial of service (buffer overflow and system crash) or     possibly gain privileges via a crafted NL80211_CMD_FRAME     Netlink packet (bnc#1049645).

  - CVE-2017-7542: The ip6_find_1stfragopt function in     net/ipv6/output_core.c in the Linux kernel allowed local     users to cause a denial of service (integer overflow and     infinite loop) by leveraging the ability to open a raw     socket (bnc#1049882).

  - CVE-2017-8831: The saa7164_bus_get function in     drivers/media/pci/saa7164/saa7164-bus.c in the Linux     kernel allowed local users to cause a denial of service     (out-of-bounds array access) or possibly have     unspecified other impact by changing a certain     sequence-number value, aka a 'double fetch'     vulnerability (bnc#1037994).

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

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.

We recommend that you upgrade your linux packages.

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

  - CVE-2017-15649: net/packet/af_packet.c in the Linux     kernel allowed 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, a different vulnerability     than CVE-2017-6346 (bnc#1064388).

  - CVE-2015-9004: kernel/events/core.c in the Linux kernel     mishandled counter grouping, which allowed local users     to gain privileges via a crafted application, related to     the perf_pmu_register and perf_event_open functions     (bnc#1037306).

  - CVE-2016-10229: udp.c in the Linux kernel allowed remote     attackers to execute arbitrary code via UDP traffic that     triggers an unsafe second checksum calculation during     execution of a recv system call with the MSG_PEEK flag     (bnc#1032268).

  - CVE-2016-9604: The handling of keyrings starting with     '.' in KEYCTL_JOIN_SESSION_KEYRING, which could have     allowed local users to manipulate privileged keyrings,     was fixed (bsc#1035576)

  - CVE-2017-1000363: Linux drivers/char/lp.c Out-of-Bounds     Write. Due to a missing bounds check, and the fact that     parport_ptr integer is static, a 'secure boot' kernel     command line adversary (can happen due to bootloader     vulns, e.g. Google Nexus 6's CVE-2016-10277, where due     to a vulnerability the adversary has partial control     over the command line) can overflow the parport_nr array     in the following code, by appending many (>LP_NO)     'lp=none' arguments to the command line (bnc#1039456).

  - CVE-2017-1000365: The Linux Kernel imposes a size     restriction on the arguments and environmental strings     passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the     size), but did not take the argument and environment     pointers into account, which allowed attackers to bypass     this limitation. (bnc#1039354).

  - CVE-2017-1000380: sound/core/timer.c in the Linux kernel     is vulnerable to a data race in the ALSA /dev/snd/timer     driver resulting in local users being able to read     information belonging to other users, i.e.,     uninitialized memory contents may be disclosed when a     read and an ioctl happen at the same time (bnc#1044125).

  - CVE-2017-10661: Race condition in fs/timerfd.c in the     Linux kernel allowed local users to gain privileges or     cause a denial of service (list corruption or     use-after-free) via simultaneous file-descriptor     operations that leverage improper might_cancel queueing     (bnc#1053152).

  - CVE-2017-11176: The mq_notify function in the Linux     kernel did not set the sock pointer to NULL upon entry     into the retry logic. During a user-space close of a     Netlink socket, it allowed attackers to cause a denial     of service (use-after-free) or possibly have unspecified     other impact (bnc#1048275).

  - CVE-2017-12153: A security flaw was discovered in the     nl80211_set_rekey_data() function in     net/wireless/nl80211.c in the Linux kernel This function     did not check whether the required attributes are     present in a Netlink request. This request can be issued     by a user with the CAP_NET_ADMIN capability and may     result in a NULL pointer dereference and system crash     (bnc#1058410).

  - CVE-2017-12154: The prepare_vmcs02 function in     arch/x86/kvm/vmx.c in the Linux kernel did not ensure     that the 'CR8-load exiting' and 'CR8-store exiting' L0     vmcs02 controls exist in cases where L1 omits the 'use     TPR shadow' vmcs12 control, which allowed KVM L2 guest     OS users to obtain read and write access to the hardware     CR8 register (bnc#1058507).

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 :

  - 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-2015-8374i1/4%0

  - crypto/pcrypt.c in the Linux kernel, before 4.14.13,     mishandles freeing instances, allowing a local user     able to access the AF_ALG-based AEAD interface     (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt     (CONFIG_CRYPTO_PCRYPT) to cause a denial of service     (kfree of an incorrect pointer) or possibly have     unspecified other impact by executing a crafted     sequence of system calls. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-18075i1/4%0

  - An elevation of privilege vulnerability in the Qualcomm     Wi-Fi driver could enable a local malicious application     to execute arbitrary code within the context of the     kernel. This issue is rated as High because it first     requires compromising a privileged process. Product:
    Android. Versions: N/A. Android ID: A-32835279.
    References: QC-CR#1096945.(CVE-2017-0523i1/4%0

  - The saa7164_bus_get function in     drivers/media/pci/saa7164/saa7164-bus.c in the Linux     kernel through 4.10.14 allows local users to cause a     denial of service (out-of-bounds array access) or     possibly have unspecified other impact by changing a     certain sequence-number value, aka a 'double fetch'     vulnerability.(CVE-2017-8831i1/4%0

  - A flaw was found in the way the Linux kernel's splice()     system call validated its parameters. On certain file     systems, a local, unprivileged user could use this flaw     to write past the maximum file size, and thus crash the     system.(CVE-2014-7822i1/4%0

  - The vc4_get_bcl function in     drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM     driver in the Linux kernel before 4.9.7 does not set an     errno value upon certain overflow detections allowing     local users to cause a denial of service (incorrect     pointer dereference and OOPS) via inconsistent size     values in a VC4_SUBMIT_CL ioctl call.(CVE-2017-5577i1/4%0

  - In fs/ocfs2/cluster/nodemanager.c in the Linux kernel     before 4.15, local users can cause a denial of service     (NULL pointer dereference and BUG) because a required     mutex is not used.(CVE-2017-18216i1/4%0

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets     implementation in the Linux kernel networking subsystem     handled synchronization while creating the TPACKET_V3     ring buffer. A local user able to open a raw packet     socket (requires the CAP_NET_RAW capability) could use     this flaw to elevate their privileges on the     system.(CVE-2016-8655i1/4%0

  - An exploitable memory corruption flaw was found in the     Linux kernel. The append path can be erroneously     switched from UFO to non-UFO in ip_ufo_append_data()     when building an UFO packet with MSG_MORE option. If     unprivileged user namespaces are available, this flaw     can be exploited to gain root     privileges.(CVE-2017-1000112i1/4%0

  - A security flaw was found in the Linux kernel in a way     that the cleancache subsystem clears an inode after the     final file truncation (removal). The new file created     with the same inode may contain leftover pages from     cleancache and the old file data instead of the new     one.(CVE-2018-16862i1/4%0

  - arch/arm64/ include /asm/pgtable.h in the Linux kernel     before 3.15-rc5-next-20140519, as used in Android     before 2016-07-05 on Nexus 5X and 6P devices,     mishandles execute-only pages, which allows attackers     to gain privileges via a crafted application, aka     Android internal bug 28557020.(CVE-2014-9803i1/4%0

  - A heap-buffer overflow vulnerability was found in the     arcmsr_iop_message_xfer() function in     'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux     kernel through 4.8.2. The function does not restrict a     certain length field, which allows local users to gain     privileges or cause a denial of service via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can     potentially cause kernel heap corruption and arbitrary     kernel code execution.(CVE-2016-7425i1/4%0

  - An issue was discovered in the Linux kernel before     4.18.11. The ipddp_ioctl function in     drivers/net/appletalk/ipddp.c allows local users to     obtain sensitive kernel address information by     leveraging CAP_NET_ADMIN to read the ipddp_route dev     and next fields via an SIOCFINDIPDDPRT ioctl     call.(CVE-2018-20511i1/4%0

  - A memory leak in the irda_bind function in     net/irda/af_irda.c in the Linux kernel, through 4.16,     allows local users to cause a denial of service due to     a memory consumption by repeatedly binding an AF_IRDA     socket.(CVE-2018-6554i1/4%0

  - sound/core/timer.c in the Linux kernel before 4.4.1     employs a locking approach that does not consider slave     timer instances, which allows local users to cause a     denial of service (race condition, use-after-free, and     system crash) via a crafted ioctl     call.(CVE-2016-2547i1/4%0

  - Buffer overflow in the complete_emulated_mmio function     in arch/x86/kvm/x86.c in the Linux kernel before 3.13.6     allows guest OS users to execute arbitrary code on the     host OS by leveraging a loop that triggers an invalid     memory copy affecting certain cancel_work_item     data.(CVE-2014-0049i1/4%0

  - An issue was discovered in the F2FS filesystem code in     the Linux kernel in fs/f2fs/inode.c. A denial of     service due to a slab out-of-bounds read can occur for     a crafted f2fs filesystem image in which FI_EXTRA_ATTR     is set in an inode.(CVE-2018-13098i1/4%0

  - A vulnerability was found in the Linux kernel where     having malicious IP options present would cause the     ipv4_pktinfo_prepare() function to drop/free the dst.
    This could result in a system crash or possible     privilege escalation.(CVE-2017-5970i1/4%0

  - In the Linux kernel's vmw_gb_surface_define_ioctl()     function, in 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c'     file, a 'req-i1/4zmip_levels' is a user-controlled value     which is later used as a loop count limit. This allows     local unprivileged user to cause a denial of service by     a kernel lockup via a crafted ioctl call for a     '/dev/dri/renderD*' device.(CVE-2017-7346i1/4%0

  - It was found that the NFSv4 server in the Linux kernel     did not properly validate layout type when processing     NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A     remote attacker could use this flaw to soft-lockup the     system and thus cause denial of     service.(CVE-2017-8797i1/4%0
