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 industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions past bounds check. The flaw     relies on the presence of a precisely-defined     instruction sequence in the privileged code and the     fact that memory writes occur to an address which     depends on the untrusted value. Such writes cause an     update 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 influence speculative execution     and/or read privileged memory by conducting targeted     cache side-channel attacks.(CVE-2018-3693)

  - A flaw named SegmentSmack was found in the way the     Linux kernel handled specially crafted TCP packets. A     remote attacker could use this flaw to trigger time and     calculation expensive calls to tcp_collapse_ofo_queue()     and tcp_prune_ofo_queue() functions by sending     specially modified packets within ongoing TCP sessions     which could lead to a CPU saturation and hence a denial     of service on the system. Maintaining the denial of     service condition requires continuous two-way TCP     sessions to a reachable open port, thus the attacks     cannot be performed using spoofed IP     addresses.(CVE-2018-5390)

  - It was found that the raw midi kernel driver does not     protect against concurrent access which leads to a     double realloc (double free) in     snd_rawmidi_input_params() and     snd_rawmidi_output_status() which are part of     snd_rawmidi_ioctl() handler in rawmidi.c file. A     malicious local attacker could possibly use this for     privilege escalation.(CVE-2018-10902)

  - Integer overflow in the aio_setup_single_vector     function in fs/aio.c in the Linux kernel 4.0 allows     local users to cause a denial of service or possibly     have unspecified other impact via a large AIO iovec.
    NOTE: this vulnerability exists because of a     CVE-2012-6701 regression.(CVE-2015-8830)

  - A flaw was found in the Linux networking subsystem     where a local attacker with CAP_NET_ADMIN capabilities     could cause an out-of-bounds memory access by creating     a smaller-than-expected ICMP header and sending to its     destination via sendto().(CVE-2016-8399)

  - Out-of-bounds kernel heap access vulnerability was     found in xfrm, kernel's IP framework for transforming     packets. An error dealing with netlink messages from an     unprivileged user leads to arbitrary read/write and     privilege escalation.(CVE-2017-7184)

  - The Linux kernel was found to be vulnerable to a NULL     pointer dereference bug in the __netlink_ns_capable()     function in the net/netlink/af_netlink.c file. A local     attacker could exploit this when a net namespace with a     netnsid is assigned to cause a kernel panic and a     denial of service.i1/4^CVE-2018-14646i1/4%0

  - A flaw was found where the kernel truncated the value     used to indicate the size of a buffer which it would     later become zero using an untruncated value. This can     corrupt memory outside of the original     allocation.(CVE-2017-9725)

  - A bug in the 32-bit compatibility layer of the ioctl     handling code of the v4l2 video driver in the Linux     kernel has been found. A memory protection mechanism     ensuring that user-provided buffers always point to a     userspace memory were disabled, allowing destination     address to be in a kernel space. This flaw could be     exploited by an attacker to overwrite a kernel memory     from an unprivileged userspace process, leading to     privilege escalation.(CVE-2017-13166)

  - 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-2017-5754 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. Note:
    CVE-2017-5754 affects Intel x86-64 microprocessors. AMD     x86-64 microprocessors are not affected by this     issue.(CVE-2017-5754)

  - 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-2017-5753 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)

  - A flaw was found in the Linux kernel's skcipher     component, which affects the skcipher_recvmsg function.
    Attackers using a specific input can lead to a     privilege escalation.i1/4^CVE-2017-13215i1/4%0

  - The tcpmss_mangle_packet function in     net/netfilter/xt_TCPMSS.c in the Linux kernel before     4.11, and 4.9.x before 4.9.36, allows remote attackers     to cause a denial of service (use-after-free and memory     corruption) or possibly have unspecified other impact     by leveraging the presence of xt_TCPMSS in an iptables     action. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.i1/4^CVE-2017-18017i1/4%0

  - A kernel data leak due to an out-of-bound read was     found in the Linux kernel in     inet_diag_msg_sctp{,l}addr_fill() and     sctp_get_sctp_info() functions present since version     4.7-rc1 through version 4.13. A data leak happens when     these functions fill in sockaddr data structures used     to export socket's diagnostic information. As a result,     up to 100 bytes of the slab data could be leaked to a     userspace.i1/4^CVE-2017-7558i1/4%0

  - Use-after-free vulnerability in the snd_pcm_info()     function in the ALSA subsystem in the Linux kernel     allows attackers to induce a kernel memory corruption     and possibly crash or lock up a system. Due to the     nature of the flaw, a privilege escalation cannot be     fully ruled out, although we believe it is     unlikely.i1/4^CVE-2017-0861i1/4%0

  - Improper validation in the bnx2x network card driver of     the Linux kernel version 4.15 can allow for denial of     service (DoS) attacks via a packet with a gso_size     larger than ~9700 bytes. Untrusted guest VMs can     exploit this vulnerability in the host machine, causing     a crash in the network card.i1/4^CVE-2018-1000026i1/4%0

  - An error in the '_sctp_make_chunk()' function     (net/sctp/sm_make_chunk.c) when handling SCTP, packet     length can be exploited by a malicious local user to     cause a kernel crash and a DoS.i1/4^CVE-2018-5803i1/4%0

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

  - The hid_input_field function in drivers/hid/hid-core.c     in the Linux kernel before 4.6 allows physically     proximate attackers to obtain sensitive information     from kernel memory or cause a denial of service     (out-of-bounds read) by connecting a device, as     demonstrated by a Logitech DJ receiver.(CVE-2016-7915)

  - In the Linux kernel through 4.14.13,     drivers/block/loop.c mishandles lo_release     serialization, which allows attackers to cause a denial     of service (__lock_acquire use-after-free) or possibly     have unspecified other impact.(CVE-2018-5344)

  - In the Linux kernel through 4.14.13, the     rds_cmsg_atomic() function in 'net/rds/rdma.c'     mishandles cases where page pinning fails or an invalid     address is supplied by a user. This can lead to a NULL     pointer dereference in rds_atomic_free_op() and thus to     a system panic.(CVE-2018-5333)

  - In the Linux kernel through 4.14.13, the     rds_message_alloc_sgs() function does not validate a     value that is used during DMA page allocation, leading     to a heap-based out-of-bounds write (related to the     rds_rdma_extra_size() function in 'net/rds/rdma.c') and     thus to a system panic. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2018-5332)

  - A flaw was found in the upstream kernel Skcipher     component. This vulnerability affects the     skcipher_recvmsg function of the component Skcipher.

  - The tcpmss_mangle_packet function in     net/netfilter/xt_TCPMSS.c in the Linux kernel before     4.11, and 4.9.x before 4.9.36, allows remote attackers     to cause a denial of service (use-after-free and memory     corruption) or possibly have unspecified other impact     by leveraging the presence of xt_TCPMSS in an iptables     action.(CVE-2017-18017)

  - The Salsa20 encryption algorithm in the Linux kernel     before 4.14.8 does not correctly handle zero-length     inputs, allowing a local attacker able to use the     AF_ALG-based skcipher interface     (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of     service (uninitialized-memory free and kernel crash) or     have unspecified other impact by executing a crafted     sequence of system calls that use the blkcipher_walk     API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 were     vulnerable.(CVE-2017-17805)

  - The HMAC implementation (crypto/hmac.c) in the Linux     kernel before 4.14.8 does not validate that the     underlying cryptographic hash algorithm is unkeyed,     allowing a local attacker able to use the AF_ALG-based     hash interface (CONFIG_CRYPTO_USER_API_HASH) and the     SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a     kernel stack buffer overflow by executing a crafted     sequence of system calls that encounter a missing SHA-3     initialization.(CVE-2017-17806)

  - he KEYS subsystem in the Linux kernel before 4.14.6     omitted an access-control check when adding a key to     the current task's 'default request-key keyring' via     the request_key() system call, allowing a local user to     use a sequence of crafted system calls to add keys to a     keyring with only Search permission (not Write     permission) to that keyring, related to     construct_get_dest_keyring() in     security/keys/request_key.c.(CVE-2017-17807)

  - The Linux Kernel 2.6.32 and later are affected by a     denial of service, by flooding the diagnostic port 0x80     an exception can be triggered leading to a kernel     panic.(CVE-2017-1000407)

  - The XFRM dump policy implementation in     net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11     allows local users to gain privileges or cause a denial     of service (use-after-free) via a crafted SO_RCVBUF     setsockopt system call in conjunction with     XFRM_MSG_GETPOLICY Netlink messages.(CVE-2017-16939)

  - The dccp_disconnect function in net/dccp/proto.c in the     Linux kernel through 4.14.3 allows local users to gain     privileges or cause a denial of service     (use-after-free) via an AF_UNSPEC connect system call     during the DCCP_LISTEN state.(CVE-2017-8824)

  - net/netfilter/nfnetlink_cthelper.c in the Linux kernel     through 4.14.4 does not require the CAP_NET_ADMIN     capability for new, get, and del operations, which     allows local users to bypass intended access     restrictions because the nfnl_cthelper_list data     structure is shared across all net     namespaces.(CVE-2017-17448)

  - Use-after-free vulnerability in the snd_pcm_info     function in the ALSA subsystem in the Linux kernel     allows attackers to gain privileges via unspecified     vectors.(CVE-2017-0861)

  - The usb_destroy_configuration function in     drivers/usb/core/config.c in the USB core subsystem in     the Linux kernel through 4.14.5 does not consider the     maximum number of configurations and interfaces before     attempting to release resources, which allows local     users to cause a denial of service (out-of-bounds write     access) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-17558)

  - The __netlink_deliver_tap_skb function in     net/netlink/af_netlink.c in the Linux kernel through     4.14.4, when CONFIG_NLMON is enabled, does not restrict     observations of Netlink messages to a single net     namespace, which allows local users to obtain sensitive     information by leveraging the CAP_NET_ADMIN capability     to sniff an nlmon interface for all Netlink activity on     the system.(CVE-2017-17449)

  - net/netfilter/xt_osf.c in the Linux kernel through     4.14.4 does not require the CAP_NET_ADMIN capability     for add_callback and remove_callback operations, which     allows local users to bypass intended access     restrictions because the xt_osf_fingers data structure     is shared across all net namespaces.(CVE-2017-17450)

  - The bnep_add_connection function in     net/bluetooth/bnep/core.c in the Linux kernel before     3.19 does not ensure that an l2cap socket is available,     which allows local users to gain privileges via a     crafted application.(CVE-2017-15868)

  - The einj_error_inject function in     drivers/acpi/apei/einj.c in the Linux kernel allows     local users to simulate hardware errors and     consequently cause a denial of service by leveraging     failure to disable APEI error injection through EINJ     when securelevel is set.(CVE-2016-3695)

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.

Race condition in the store_int_with_restart() function in cpu/mcheck/mce.c :

A race condition in the store_int_with_restart() function in arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel allows local users to cause a denial of service (panic) by leveraging root access to write to the check_interval file in a /sys/devices/system/machinecheck/machinecheck<cpu number> directory.
(CVE-2018-7995)

Out-of-bounds write via userland offsets in ebt_entry struct in netfilter/ebtables.c :

A flaw was found in the Linux kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory. (CVE-2018-1068)

A flaw was found in the Linux kernel's skcipher component, which affects the skcipher_recvmsg function. Attackers using a specific input can lead to a privilege escalation.(CVE-2017-13215)

The do_get_mempolicy() function in mm/mempolicy.c in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service (DoS) or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.(CVE-2018-10675)

A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges.(CVE-2018-10901)

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities:

  - 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-2015-2041)

  - net/rds/sysctl.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-2015-2042)

  - The xfrm_migrate() function in the     net/xfrm/xfrm_policy.c file in the Linux kernel built     with CONFIG_XFRM_MIGRATE does not verify if the dir     parameter is less than XFRM_POLICY_MAX. This allows a     local attacker to cause a denial of service (out-of-     bounds access) or possibly have unspecified other impact     by sending a XFRM_MSG_MIGRATE netlink message. This flaw     is present in the Linux kernel since an introduction of     XFRM_MSG_MIGRATE in 2.6.21-rc1, up to 4.13-rc3.
    (CVE-2017-11600)

  - A flaw was found in the Linux kernel's skcipher     component, which affects the skcipher_recvmsg function.
    Attackers using a specific input can lead to a privilege     escalation. (CVE-2017-13215)

  - The Linux kernel is vulerable to a use-after-free flaw     when Transformation User configuration     interface(CONFIG_XFRM_USER) compile-time configuration     were enabled. This vulnerability occurs while closing a     xfrm netlink socket in xfrm_dump_policy_done. A     user/process could abuse this flaw to potentially     escalate their privileges on a system. (CVE-2017-16939)

  - The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allows attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call. An     unprivileged local user could use this flaw 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 we     believe it is unlikely. (CVE-2017-8890)

  - An address corruption flaw was discovered in the Linux     kernel built with hardware breakpoint     (CONFIG_HAVE_HW_BREAKPOINT) support. While modifying a     h/w breakpoint via 'modify_user_hw_breakpoint' routine,     an unprivileged user/process could use this flaw to     crash the system kernel resulting in DoS OR to     potentially escalate privileges on a the system.
    (CVE-2018-1000199)

  - The do_get_mempolicy() function in mm/mempolicy.c in the     Linux kernel allows local users to hit a use-after-free     bug via crafted system calls and thus cause a denial of     service (DoS) or possibly have unspecified other impact.
    Due to the nature of the flaw, privilege escalation     cannot be fully ruled out. (CVE-2018-10675)

  - A flaw was found in the Linux kernel's implementation of     32-bit syscall interface for bridging. This allowed a     privileged user to arbitrarily write to a limited range     of kernel memory. (CVE-2018-1068)

  - A Floating Point Unit (FPU) state information leakage     flaw was found in the way the Linux kernel saved and     restored the FPU state during task switch. Linux kernels     that follow the Lazy FPU Restore scheme are vulnerable     to the FPU state information leakage issue. An     unprivileged local attacker could use this flaw to read     FPU state bits by conducting targeted cache side-channel     attacks, similar to the Meltdown vulnerability disclosed     earlier this year. (CVE-2018-3665)

  - A flaw was found in the way the Linux kernel handled     exceptions delivered after a stack switch operation via     Mov SS or Pop SS instructions. During the stack switch     operation, the processor did not deliver interrupts and     exceptions, rather they are delivered once the first     instruction after the stack switch is executed. An     unprivileged system user could use this flaw to crash     the system kernel resulting in the denial of service.
    (CVE-2018-8897)

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

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:1190 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * A flaw was found in the implementation of the fill buffer, a mechanism used by modern CPUs when a     cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page     fault, the execution will continue speculatively with incorrect data from the fill buffer while the data     is fetched from higher level caches. This response time can be measured to infer data in the fill buffer.
    (CVE-2018-12130)

    * Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of     writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore     Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into     these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed     processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use     this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)

    * Microprocessors use a load port subcomponent to perform load operations from memory or IO. During     a load operation, the load port receives data from the memory or IO subsystem and then provides the data     to the CPU registers and operations in the CPUs pipelines. Stale load operations results are stored in     the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an     attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a     timing side-channel. (CVE-2018-12127)

    * Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated     user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11091)

    * kernel: Buffer overflow in firewire driver via crafted incoming packets (CVE-2016-8633)

    * kernel: crypto: privilege escalation in skcipher_recvmsg function (CVE-2017-13215)

    * Kernel: ipsec: xfrm: use-after-free leading to potential privilege escalation (CVE-2017-16939)

    * kernel: Out-of-bounds write via userland offsets in ebt_entry struct in netfilter/ebtables.c     (CVE-2018-1068)

    * kernel: Use-after-free due to race condition in AF_PACKET implementation (CVE-2018-18559)

    * kernel: media: use-after-free in [tuner-xc2028] media driver (CVE-2016-7913)

    * kernel: Out-of-bounds access via an XFRM_MSG_MIGRATE xfrm Netlink message (CVE-2017-11600)

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

    * kernel: Unallocated memory access by malicious USB device via bNumInterfaces overflow (CVE-2017-17558)

    * Kernel: FPU state information leakage via lazy FPU restore (CVE-2018-3665)

    Bug Fix(es):

    * update the MRG 2.5.z 3.10 kernel-rt sources (BZ#1692711)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

An update for kernel is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es) :

* Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks.
(CVE-2018-3620, CVE-2018-3646)

* An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update 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 influence speculative execution and/or read privileged memory by conducting targeted cache side-channel attacks.
(CVE-2018-3693)

* A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses.
(CVE-2018-5390)

* kernel: crypto: privilege escalation in skcipher_recvmsg function (CVE-2017-13215)

Bug Fix(es) :

These updated kernel packages include also numerous bug fixes. Space precludes documenting all of the bug fixes in this advisory. See the descriptions in the related Knowledge Article :

https://access.redhat.com/articles/3527791

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

  - CVE-2017-5715: Systems with microprocessors utilizing     speculative execution and indirect branch prediction may     allow unauthorized disclosure of information to an     attacker with local user access via a side-channel     analysis (bnc#1068032). The previous fix using CPU     Microcode has been complemented by building the Linux     Kernel with return trampolines aka 'retpolines'.

  - CVE-2017-18079: drivers/input/serio/i8042.c allowed     attackers to cause a denial of service (NULL pointer     dereference and system crash) or possibly have     unspecified other impact because the port->exists value     can change after it is validated (bnc#1077922)

  - CVE-2015-1142857: Prevent guests from sending ethernet     flow control pause frames via the PF (bnc#1077355)

  - CVE-2017-17741: KVM allowed attackers to obtain     potentially sensitive information from kernel memory,     aka a write_mmio stack-based out-of-bounds read     (bnc#1073311)

  - CVE-2017-13215: Prevent elevation of privilege     (bnc#1075908)

  - CVE-2018-1000004: Prevent race condition in the sound     system, this could have lead a deadlock and denial of     service condition (bnc#1076017)

  - CVE-2017-17806: The HMAC implementation did not validate     that the underlying cryptographic hash algorithm is     unkeyed, allowing a local attacker able to use the     AF_ALG-based hash interface     (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash     algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel     stack-based buffer overflow by executing a crafted     sequence of system calls that encounter a missing SHA-3     initialization (bnc#1073874)

  - CVE-2017-17805: The Salsa20 encryption algorithm did not     correctly handle zero-length inputs, allowing a local     attacker able to use the AF_ALG-based skcipher interface     (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of     service (uninitialized-memory free and kernel crash) or     have unspecified other impact by executing a crafted     sequence of system calls that use the blkcipher_walk     API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 were     vulnerable (bnc#1073792)

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