    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - 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 bio_map_user_iov and bio_unmap_user functions in block/bio.c in the Linux kernel before 4.13.8 do unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page. The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes 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.(CVE-2017-12190) - The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel before 4.13.11 mishandles node splitting, which allows local users to cause a denial of service (NULL pointer dereference and panic) via a crafted application, as demonstrated by the keyring key type, and key addition and link creation operations.(CVE-2017-12193) - The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel through 4.12.3 allows local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket.(CVE-2017-7542) - 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 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) - 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 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 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

    "According to the versions of the kernel packages installed, the
    EulerOS installation on the remote host is affected by the following
    vulnerabilities :
    
      - 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 bio_map_user_iov and bio_unmap_user functions in
        block/bio.c in the Linux kernel before 4.13.8 do
        unbalanced refcounting when a SCSI I/O vector has small
        consecutive buffers belonging to the same page. The
        bio_add_pc_page function merges them into one, but the
        page reference is never dropped. This causes 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.(CVE-2017-12190)
    
      - The assoc_array_insert_into_terminal_node function in
        lib/assoc_array.c in the Linux kernel before 4.13.11
        mishandles node splitting, which allows local users to
        cause a denial of service (NULL pointer dereference and
        panic) via a crafted application, as demonstrated by
        the keyring key type, and key addition and link
        creation operations.(CVE-2017-12193)
    
      - The ip6_find_1stfragopt function in
        net/ipv6/output_core.c in the Linux kernel through
        4.12.3 allows local users to cause a denial of service
        (integer overflow and infinite loop) by leveraging the
        ability to open a raw socket.(CVE-2017-7542)
    
      - 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 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)
    
      - 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 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 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

        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)

        (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)

    "According to the version of the vzkernel package and the
    readykernel-patch installed, the Virtuozzo installation on the remote
    host is affected by the following vulnerabilities :
    
      - Linux kernel before version 4.16-rc7 is vulnerable to a
        null pointer dereference in dccp_write_xmit() function
        in net/dccp/output.c in that allows a local user to
        cause a denial of service by a number of certain
        crafted system calls.
    
      - It was found that _sctp_make_chunk() function did not
        check if the chunk length for INIT and INIT_ACK packets
        was within the allowed limits. A local attacker could
        exploit this to trigger a kernel crash.
    
      - It was discovered that nfnl_cthelper_list structure was
        accessible to any user with CAP_NET_ADMIN capability in
        a network namespace. An unprivileged local user could
        exploit that to affect netfilter conntrack helpers on
        the host.
    
      - It was discovered that a nlmon link inside a child
        network namespace was not restricted to that namespace.
        An unprivileged local user could exploit that to
        monitor system-wide netlink activity.
    
      - The KEYS subsystem in the Linux kernel omitted an
        access-control check when writing a key to the current
        task's default keyring, allowing a local user to bypass
        security checks to the keyring. This compromises the
        validity of the keyring for those who rely on it.
    
      - 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. This
        allows local users to bypass intended access
        restrictions because the xt_osf_fingers data structure
        is shared across all network namespaces.

    description block directly from the Virtuozzo security advisory.
    Tenable has attempted to automatically clean and format it as much as

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - 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-2017-16538 Andrey Konovalov reported that the dvb-usb-lmedm04 media driver did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). - CVE-2017-16644 Andrey Konovalov reported that the hdpvr media driver did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). - CVE-2017-16995 Jann Horn discovered that the Extended BPF verifier did not correctly model the behaviour of 32-bit load instructions. A local user can use this for privilege escalation. - CVE-2017-17448 Kevin Cernekee discovered that the netfilter subsystem allowed users with the CAP_NET_ADMIN capability in any user namespace, not just the root namespace, to enable and disable connection tracking helpers. This could lead to denial of service, violation of network security policy, or have other impact. - CVE-2017-17449 Kevin Cernekee discovered that the netlink subsystem allowed users with the CAP_NET_ADMIN capability in any user namespace to monitor netlink traffic in all net namespaces, not just those owned by that user namespace. This could lead to exposure of sensitive information. - CVE-2017-17450 Kevin Cernekee discovered that the xt_osf module allowed users with the CAP_NET_ADMIN capability in any user namespace to modify the global OS fingerprint list. - CVE-2017-17558 Andrey Konovalov reported that that USB core did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or memory corruption), or possibly for privilege escalation. - CVE-2017-17712 Mohamed Ghannam discovered a race condition in the IPv4 raw socket implementation. A local user could use this to obtain sensitive information from the kernel. - CVE-2017-17741 Dmitry Vyukov reported that the KVM implementation for x86 would over-read data from memory when emulating an MMIO write if the kvm_mmio tracepoint was enabled. A guest virtual machine might be able to use this to cause a denial of service (crash). - CVE-2017-17805 It was discovered that some implementations of the Salsa20 block cipher did not correctly handle zero-length input. A local user could use this to cause a denial of service (crash) or possibly have other security impact. - CVE-2017-17806 It was discovered that the HMAC implementation could be used with an underlying hash algorithm that requires a key, which was not intended.

        instructions. A local user can use this for privilege
        escalation.
    
      - CVE-2017-17448
        Kevin Cernekee discovered that the netfilter subsystem
        allowed users with the CAP_NET_ADMIN capability in any
        user namespace, not just the root namespace, to enable
        and disable connection tracking helpers. This could lead
        to denial of service, violation of network security
        policy, or have other impact.
    
      - CVE-2017-17449
        Kevin Cernekee discovered that the netlink subsystem
        allowed users with the CAP_NET_ADMIN capability in any
        user namespace to monitor netlink traffic in all net
        namespaces, not just those owned by that user namespace.
        This could lead to exposure of sensitive information.
    
      - CVE-2017-17450
        Kevin Cernekee discovered that the xt_osf module allowed
        users with the CAP_NET_ADMIN capability in any user
        namespace to modify the global OS fingerprint list.
    
      - CVE-2017-17558
        Andrey Konovalov reported that that USB core did not
        correctly handle some error conditions during
        initialisation. A physically present user with a
        specially designed USB device can use this to cause a
        denial of service (crash or memory corruption), or
        possibly for privilege escalation.
    
      - CVE-2017-17712
        Mohamed Ghannam discovered a race condition in the IPv4
        raw socket implementation. A local user could use this
        to obtain sensitive information from the kernel.
    
      - CVE-2017-17741
        Dmitry Vyukov reported that the KVM implementation for
        x86 would over-read data from memory when emulating an
        MMIO write if the kvm_mmio tracepoint was enabled. A
        guest virtual machine might be able to use this to cause
        a denial of service (crash).
    
      - CVE-2017-17805
        It was discovered that some implementations of the
        Salsa20 block cipher did not correctly handle
        zero-length input. A local user could use this to cause
        a denial of service (crash) or possibly have other
        security impact.
    
      - CVE-2017-17806
        It was discovered that the HMAC implementation could be
        used with an underlying hash algorithm that requires a
        key, which was not intended. A local user could use this
        to cause a denial of service (crash or memory
        corruption), or possibly for privilege escalation.
    
      - CVE-2017-17807
        Eric Biggers discovered that the KEYS subsystem lacked a
        check for write permission when adding keys to a
        process's default keyring. A local user could use this
        to cause a denial of service or to obtain sensitive
        information.
    
      - CVE-2017-17862
        Alexei Starovoitov discovered that the Extended BPF
        verifier ignored unreachable code, even though it would
        still be processed by JIT compilers. This could possibly
        be used by local users for denial of service. It also
        increases the severity of bugs in determining
        unreachable code.
    
      - CVE-2017-17863
        Jann Horn discovered that the Extended BPF verifier did
        not correctly model pointer arithmetic on the stack
        frame pointer. A local user can use this for privilege
        escalation.
    
      - CVE-2017-17864
        Jann Horn discovered that the Extended BPF verifier
        could fail to detect pointer leaks from conditional

        information in order to exploit other vulnerabilities.
    
      - 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.
    
      - CVE-2017-1000410
        Ben Seri reported that the Bluetooth subsystem did not
        correctly handle short EFS information elements in L2CAP
        messages. An attacker able to communicate over Bluetooth
        could use this to obtain sensitive information from the
        kernel.
    
    The various problems in the Extended BPF verifier can be mitigated by
    disabling use of Extended BPF by unprivileged users:sysctl
    kernel.unprivileged_bpf_disabled=1
    
    Debian disables unprivileged user namespaces by default, but if they
    are enabled (via the kernel.unprivileged_userns_clone sysctl) then
    CVE-2017-17448 can be exploited by any local user."

    NASL idVIRTUOZZO_VZA-2018-029.NASL
    descriptionAccording to the versions of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo 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 (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: This update fixes the 32-bit compatibility layer on x86-64 processors, i.e. when 32-bit containers are executed on 64-bit processors. - 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. - The KEYS subsystem in the Linux kernel omitted an access-control check when writing a key to the current task
