The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2017-0057 for details.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:0439 advisory.

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

    * A denial of service flaw was found in the way the Linux kernel's IPv6     implementation processed IPv6 router advertisement (RA) packets.
    An attacker able to send a large number of RA packets to a target system     could potentially use this flaw to crash the target system. (CVE-2014-2309,     Important)

    * A flaw was found in the way the Linux kernel's netfilter connection     tracking implementation for Datagram Congestion Control Protocol (DCCP)     packets used the skb_header_pointer() function. A remote attacker could use     this flaw to send a specially crafted DCCP packet to crash the system or,     potentially, escalate their privileges on the system. (CVE-2014-2523,     Important)

    * A flaw was found in the way the Linux kernel's CIFS implementation     handled uncached write operations with specially crafted iovec structures.
    An unprivileged local user with access to a CIFS share could use this flaw     to crash the system, leak kernel memory, or, potentially, escalate their     privileges on the system. (CVE-2014-0069, Moderate)

    * A flaw was found in the way the Linux kernel handled pending Floating     Pointer Unit (FPU) exceptions during the switching of tasks. A local     attacker could use this flaw to terminate arbitrary processes on the     system, causing a denial of service, or, potentially, escalate their     privileges on the system. Note that this flaw only affected systems using     AMD CPUs on both 32-bit and 64-bit architectures. (CVE-2014-1438, Moderate)

    * It was found that certain protocol handlers in the Linux kernel's     networking implementation could set the addr_len value without initializing     the associated data structure. A local, unprivileged user could use this     flaw to leak kernel stack memory to user space using the recvmsg, recvfrom,     and recvmmsg system calls. (CVE-2013-7263, CVE-2013-7265, Low)

    * An information leak flaw was found in the Linux kernel's netfilter     connection tracking IRC NAT helper implementation that could allow a remote     attacker to disclose portions of kernel stack memory during IRC DCC (Direct     Client-to-Client) communication over NAT. (CVE-2014-1690, Low)

    * A denial of service flaw was discovered in the way the Linux kernel's     SELinux implementation handled files with an empty SELinux security     context. A local user who has the CAP_MAC_ADMIN capability could use this     flaw to crash the system. (CVE-2014-1874, Low)

    Red Hat would like to thank Al Viro for reporting CVE-2014-0069.
    The CVE-2014-1690 issue was discovered by Daniel Borkmann of Red Hat.

    This update also fixes several bugs and adds multiple enhancements.
    Documentation for these changes will be available shortly from the     Technical Notes document linked to in the References section.

    Users are advised to upgrade to these updated packages, which upgrade the     kernel-rt kernel to version kernel-rt-3.10.33-rt32.33, correct these     issues, and fix the bugs and add the enhancements noted in the Red Hat     Enterprise MRG 2 Technical Notes. The system must be rebooted for this     update to take effect.

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.

Multiple vulnerabilities has been found and corrected in the Linux kernel :

kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number (CVE-2014-3917).

The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification (CVE-2014-3153).

Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large amount of network traffic that triggers certain list deletions (CVE-2014-2672).

The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the
__skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced (CVE-2014-3144).

The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced (CVE-2014-3145).

Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the Linux kernel through 3.14.1 allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that leverages an improperly managed reference counter (CVE-2014-2851).

The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the LECHO !OPOST case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings (CVE-2014-0196).

The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device (CVE-2014-1738).

The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device (CVE-2014-1737).

The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a bind system call for an RDS socket on a system that lacks RDS transports (CVE-2014-2678).

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).

The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count the addition of routes, which allows remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets (CVE-2014-2309).

Multiple array index errors in drivers/hid/hid-multitouch.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_MULTITOUCH is enabled, allow physically proximate attackers to cause a denial of service (heap memory corruption, or NULL pointer dereference and OOPS) via a crafted device (CVE-2013-2897).

net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a DCCP packet that triggers a call to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error function (CVE-2014-2523).

Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via network traffic that improperly interacts with the WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c (CVE-2014-2706).

The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk (CVE-2014-0101).

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).

arch/s390/kernel/head64.S in the Linux kernel before 3.13.5 on the s390 platform does not properly handle attempted use of the linkage stack, which allows local users to cause a denial of service (system crash) by executing a crafted instruction (CVE-2014-2039).

Buffer overflow in virt/kvm/irq_comm.c in the KVM subsystem in the Linux kernel before 3.2.24 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to Message Signaled Interrupts (MSI), irq routing entries, and an incorrect check by the setup_routing_entry function before invoking the kvm_set_irq function (CVE-2012-2137).

The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context (CVE-2014-1874).

Tenable has extracted the preceding description block directly from the Oracle 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.

* A flaw was found in the way the get_rx_bufs() function in the vhost_net implementation in the Linux kernel handled error conditions reported by the vhost_get_vq_desc() function. A privileged guest user could use this flaw to crash the host. (CVE-2014-0055, Important)

* 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, Important)

* A flaw was found in the way the Linux kernel's CIFS implementation handled uncached write operations with specially crafted iovec structures. An unprivileged local user with access to a CIFS share could use this flaw to crash the system, leak kernel memory, or, potentially, escalate their privileges on the system. Note: the default cache settings for CIFS mounts on Scientific Linux 6 prohibit a successful exploitation of this issue. (CVE-2014-0069, Moderate)

* A heap-based buffer overflow flaw was found in the Linux kernel's cdc- wdm driver, used for USB CDC WCM device management. An attacker with physical access to a system could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1860, Low)

The system must be rebooted for this update to take effect.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:0328 advisory.

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

    * A flaw was found in the way the get_rx_bufs() function in the vhost_net     implementation in the Linux kernel handled error conditions reported by the     vhost_get_vq_desc() function. A privileged guest user could use this flaw     to crash the host. (CVE-2014-0055, Important)

    * 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, Important)

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-0328 advisory.

  - Heap-based buffer overflow in the wdm_in_callback function in drivers/usb/class/cdc-wdm.c in the Linux     kernel before 3.8.4 allows physically proximate attackers to cause a denial of service (system crash) or     possibly execute arbitrary code via a crafted cdc-wdm USB device. (CVE-2013-1860)

  - The get_rx_bufs function in drivers/vhost/net.c in the vhost-net subsystem in the Linux kernel package     before 2.6.32-431.11.2 on Red Hat Enterprise Linux (RHEL) 6 does not properly handle vhost_get_vq_desc     errors, which allows guest OS users to cause a denial of service (host OS crash) via unspecified vectors.
    (CVE-2014-0055)

  - 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)

  - The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not     validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which     allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an     SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk.
    (CVE-2014-0101)

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

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

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.

The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context.

The Linux kernel before 3.12.4 updates certain length values before ensuring that associated data structures have 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, related to net/ipv4/ping.c, net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and net/ipv6/udp.c.

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.
