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 manipulation with an unknown input leads to a     privilege escalation vulnerability.(CVE-2017-13215)

  - 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)
