arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in certain error cases, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.

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 :

  - In the Linux kernel through 4.19, a use-after-free can     occur due to a race condition between fanout_add from     setsockopt and bind on an AF_PACKET socket. This issue     exists because of the     15fe076edea787807a7cdc168df832544b58eba6 incomplete fix     for a race condition. The code mishandles a certain     multithreaded case involving a packet_do_bind     unregister action followed by a packet_notifier     register action. Later, packet_release operates on only     one of the two applicable linked lists. The attacker     can achieve Program Counter control.(CVE-2018-18559i1/4%0

  - The acpi_ns_terminate() function in     drivers/acpi/acpica/nsutils.c in the Linux kernel     before 4.12 does not flush the operand cache and causes     a kernel stack dump. A local users could obtain     sensitive information from kernel memory and bypass the     KASLR protection mechanism (in the kernel through 4.9)     via a crafted ACPI table.(CVE-2017-11472i1/4%0

  - Race condition in net/packet/af_packet.c in the Linux     kernel allows local users to cause a denial of service     (use-after-free) or possibly have unspecified other     impact via a multithreaded application that makes     PACKET_FANOUT setsockopt system calls.(CVE-2017-6346i1/4%0

  - Multiple race conditions in ipc/shm.c in the Linux     kernel before 3.12.2 allow local users to cause a     denial of service (use-after-free and system crash) or     possibly have unspecified other impact via a crafted     application that uses shmctl IPC_RMID operations in     conjunction with other shm system     calls.(CVE-2013-7026i1/4%0

  - An issue was discovered in the Linux kernel. A NULL     pointer dereference and panic in hfsplus_lookup() in     the fs/hfsplus/dir.c function can occur when opening a     file (that is purportedly a hard link) in an hfs+     filesystem that has malformed catalog data, and is     mounted read-only without a metadata     directory.(CVE-2018-14617i1/4%0

  - The treo_attach function in drivers/usb/serial/visor.c     in the Linux kernel before 4.5 allows physically     proximate attackers to cause a denial of service (NULL     pointer dereference and system crash) or possibly have     unspecified other impact by inserting a USB device that     lacks a (1) bulk-in or (2) interrupt-in     endpoint.(CVE-2016-2782i1/4%0

  - An information-exposure flaw was found in the Linux     kernel where the pcpu_embed_first_chunk() function in     mm/percpu.c allows local users to obtain kernel-object     address information by reading the kernel log (dmesg).
    However, this address is not static and cannot be used     to commit a further attack.(CVE-2018-5995i1/4%0

  - Buffer overflow in net/ceph/auth_x.c in Ceph, as used     in the Linux kernel before 3.16.3, allows remote     attackers to cause a denial of service (memory     corruption and panic) or possibly have unspecified     other impact via a long unencrypted auth     ticket.(CVE-2014-6416i1/4%0

  - It was found that the Linux kernel's ptrace subsystem     allowed a traced process' instruction pointer to be set     to a non-canonical memory address without forcing the     non-sysret code path when returning to user space. A     local, unprivileged user could use this flaw to crash     the system or, potentially, escalate their privileges     on the system.Note: The CVE-2014-4699 issue only     affected systems using an Intel CPU.(CVE-2014-4699i1/4%0

  - The snd_compr_tstamp function in     sound/core/compress_offload.c in the Linux kernel     through 4.7, as used in Android before 2016-08-05 on     Nexus 5 and 7 (2013) devices, does not properly     initialize a timestamp data structure, which allows     attackers to obtain sensitive information via a crafted     application, aka Android internal bug 28770164 and     Qualcomm internal bug CR568717.(CVE-2014-9892i1/4%0

  - A flaw was found in the way the Linux kernel's ext4     file system handled the 'page size i1/4z block size'     condition when the fallocate zero range functionality     was used. A local attacker could use this flaw to crash     the system.(CVE-2015-0275i1/4%0

  - An information leak flaw was found in the way the Linux     kernel's ISO9660 file system implementation accessed     data on an ISO9660 image with RockRidge Extension     Reference (ER) records. An attacker with physical     access to the system could use this flaw to disclose up     to 255 bytes of kernel memory.(CVE-2014-9584i1/4%0

  - The pivot_root implementation in fs/namespace.c in the     Linux kernel through 3.17 does not properly interact     with certain locations of a chroot directory, which     allows local users to cause a denial of service     (mount-tree loop) via . (dot) values in both arguments     to the pivot_root system call.(CVE-2014-7970i1/4%0

  - arch/x86/kvm/emulate.c in the Linux kernel before     4.8.12 does not properly initialize Code Segment (CS)     in certain error cases, which allows local users to     obtain sensitive information from kernel stack memory     via a crafted application.(CVE-2016-9756i1/4%0

  - A flaw was found in the Linux kernel where the     swiotlb_print_info() function in lib/swiotlb.c allows     local users to obtain some kernel address information     by reading the kernel log (dmesg). This address is not     useful to commit a further attack.(CVE-2018-5953i1/4%0

  - A flaw was found in the way the Linux kernel's file     system implementation handled rename operations in     which the source was inside and the destination was     outside of a bind mount. A privileged user inside a     container could use this flaw to escape the bind mount     and, potentially, escalate their privileges on the     system.(CVE-2015-2925i1/4%0

  - A use-after-free fault in the Linux kernel's usbtv     driver could allow an attacker to cause a denial of     service (system crash), or have unspecified other     impacts, by triggering failure of audio registration of     USB hardware using the usbtv kernel     module.(CVE-2017-17975i1/4%0

  - 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-2017-7889i1/4%0

  - A flaw was discovered in the way the kernel allows     stackable filesystems to overlay. A local attacker who     is able to mount filesystems can abuse this flaw to     escalate privileges.(CVE-2014-9922i1/4%0

  - sound/core/timer.c in the Linux kernel before 4.4.1     retains certain linked lists after a close or stop     action, which allows local users to cause a denial of     service (system crash) via a crafted ioctl call,     related to the (1) snd_timer_close and (2)
    _snd_timer_stop functions.(CVE-2016-2548i1/4%0

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-3533 advisory.

  - The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in     situations where the KERNEL_DS option is set, which allows 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. (CVE-2016-10088)

  - The filesystem implementation in the Linux kernel through 4.8.2 preserves the setgid bit during a setxattr     call, which allows local users to gain group privileges by leveraging the existence of a setgid program     with restrictions on execute permissions. (CVE-2016-7097)

  - 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. (CVE-2016-8399)

  - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause     a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large     command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write     function. (CVE-2017-7187)

  - 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)

  - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not     properly randomize the legacy base address, which makes it easier for local users to defeat the intended     restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or     setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)

  - The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly     emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS     memory consumption) by leveraging the mishandling of page references. (CVE-2017-2596)

  - arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in     certain error cases, which allows local users to obtain sensitive information from kernel stack memory via     a crafted application. (CVE-2016-9756)

(CVE-2016-8632)

  - The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not     initialize a certain integer variable, which allows local users to obtain sensitive information from     kernel stack memory by triggering failure of a get_user_ex call. (CVE-2016-9178)

  - The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6     mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via     filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba.
    (CVE-2015-8952)

  - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1     allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system     crash) via a crafted endpoints value in a USB device descriptor. (CVE-2016-3140)

  - The LLC subsystem in the Linux kernel before 4.9.13 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-2017-6345)

  - The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows     attackers to cause a denial of service (system crash) via (1) an application that makes crafted system     calls or possibly (2) IPv4 traffic with invalid IP options. (CVE-2017-5970)

  - Race condition in kernel/events/core.c in the Linux kernel before 4.9.7 allows local users to gain     privileges via a crafted application that makes concurrent perf_event_open system calls for moving a     software group into a hardware context. NOTE: this vulnerability exists because of an incomplete fix for     CVE-2016-6786. (CVE-2017-6001)

  - 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)

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

  - 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 the snd_pcm_period_elapsed function in sound/core/pcm_lib.c in the ALSA subsystem in the     Linux kernel before 4.7 allows local users to cause a denial of service (use-after-free) or possibly have     unspecified other impact via a crafted SNDRV_PCM_TRIGGER_START command. (CVE-2016-9794)

  - Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel before 4.6.3     allows local users to cause a denial of service (double free) or possibly have unspecified other impact     via a crafted application that makes sendmsg system calls, leading to a free operation associated with a     new dump that started earlier than anticipated. (CVE-2016-9806)

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

Dmitry Vyukov discovered that the KVM implementation in the Linux kernel did not properly initialize the Code Segment (CS) in certain error cases. A local attacker could use this to expose sensitive information (kernel memory).

Baozeng Ding discovered a race condition that could lead to a use-after- free in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-9794).

The openSUSE 42.1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2016-9756: KVM: x86: drop error recovery in     em_jmp_far and em_ret_far (bsc#1013038).

The following non-security bugs were fixed :

  - scsi: megaraid_sas: fix macro MEGASAS_IS_LOGICAL to     avoid regression (bsc#1014943).

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.
