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

  - The pn_recvmsg function in net/phonet/datagram.c in the     Linux kernel before 3.12.4 updates a certain length     value before ensuring that an associated data structure     has been initialized, which allows local users to     obtain sensitive information from kernel stack memory     via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system     call.(CVE-2013-7265)

  - The mISDN_sock_recvmsg function in     drivers/isdn/mISDN/socket.c in the Linux kernel before     3.12.4 does not ensure that a certain length value is     consistent with the size of an associated data     structure, which allows local users to obtain sensitive     information from kernel memory via a (1) recvfrom, (2)     recvmmsg, or (3) recvmsg system call.(CVE-2013-7266)

  - The atalk_recvmsg function in net/appletalk/ddp.c in     the Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7267)

  - The ipx_recvmsg function in net/ipx/af_ipx.c in the     Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7268)

  - The nr_recvmsg function in net/netrom/af_netrom.c in     the Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7269)

  - The packet_recvmsg function in net/packet/af_packet.c     in the Linux kernel before 3.12.4 updates a certain     length value before ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7270)

  - The x25_recvmsg function in net/x25/af_x25.c in the     Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7271)

  - The dgram_recvmsg function in net/ieee802154/dgram.c in     the Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel stack     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7281)

  - A NULL pointer dereference flaw was found in the     rds_ib_laddr_check() function in the Linux kernel's     implementation of Reliable Datagram Sockets (RDS). A     local, unprivileged user could use this flaw to crash     the system.(CVE-2013-7339)

  - A flaw was found in the way the Linux kernel's Crypto     subsystem handled automatic loading of kernel modules.
    A local user could use this flaw to load any installed     kernel module, and thus increase the attack surface of     the running kernel.(CVE-2013-7421)

  - A flaw was found in the Linux kernel's implementation     of Unix sockets. A server polling for client-socket     data could put the peer socket on a wait list the peer     socket could then close the connection, making the     reference on the wait list no longer valid. This could     lead to bypassing the permissions on a Unix socket and     packets being injected into the stream, and could also     panic the machine (denial of service).(CVE-2013-7446)

  - The compat_sys_recvmmsg function in net/compat.c in the     Linux kernel before 3.13.2, when CONFIG_X86_X32 is     enabled, allows local users to gain privileges via a     recvmmsg system call with a crafted timeout pointer     parameter.(CVE-2014-0038)

  - 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-2014-0049)

  - The cifs_iovec_write function in fs/cifs/file.c in the     Linux kernel through 3.13.5 does not properly handle     uncached write operations that copy fewer than the     requested number of bytes, which allows local users to     obtain sensitive information from kernel memory, cause     a denial of service (memory corruption and system     crash), or possibly gain privileges via a writev system     call with a crafted pointer.(CVE-2014-0069)

  - drivers/vhost/net.c in the Linux kernel before 3.13.10,     when mergeable buffers are disabled, does not properly     validate packet lengths, which allows guest OS users to     cause a denial of service (memory corruption and host     OS crash) or possibly gain privileges on the host OS     via crafted packets, related to the handle_rx and     get_rx_bufs functions.(CVE-2014-0077)

  - Race condition in the inet_frag_intern function in     net/ipv4/inet_fragment.c in the Linux kernel through     3.13.6 allows remote attackers to cause a denial of     service (use-after-free error) or possibly have     unspecified other impact via a large series of     fragmented ICMP Echo Request packets to a system with a     heavy CPU load.(CVE-2014-0100)

  - A flaw was found in the way the Linux kernel processed     an authenticated COOKIE_ECHO chunk during the     initialization of an SCTP connection. A remote attacker     could use this flaw to crash the system by initiating a     specially crafted SCTP handshake in order to trigger a     NULL pointer dereference on the system.(CVE-2014-0101)

  - The keyring_detect_cycle_iterator function in     security/keys/keyring.c in the Linux kernel through     3.13.6 does not properly determine whether keyrings are     identical, which allows local users to cause a denial     of service (OOPS) via crafted keyctl     commands.(CVE-2014-0102)

  - Use-after-free vulnerability in the skb_segment     function in net/core/skbuff.c in the Linux kernel     through 3.13.6 allows attackers to obtain sensitive     information from kernel memory by leveraging the     absence of a certain orphaning     operation.(CVE-2014-0131)

  - The ioapic_deliver function in virt/kvm/ioapic.c in the     Linux kernel through 3.14.1 does not properly validate     the kvm_irq_delivery_to_apic return value, which allows     guest OS users to cause a denial of service (host OS     crash) via a crafted entry in the redirection table of     an I/O APIC. NOTE: the affected code was moved to the     ioapic_service function before the vulnerability was     announced.(CVE-2014-0155)

  - It was found that the permission checks performed by     the Linux kernel when a netlink message was received     were not sufficient. A local, unprivileged user could     potentially bypass these restrictions by passing a     netlink socket as stdout or stderr to a more privileged     process and altering the output of this     process.(CVE-2014-0181)
