The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-3081 advisory.

    - ALSA: control: Don't access controls outside of protected regions (Lars-Peter Clausen)  [Orabug:
    19817785]  {CVE-2014-4653} {CVE-2014-4654} {CVE-2014-4655}
    - ALSA: control: Fix replacing user controls (Lars-Peter Clausen)  [Orabug: 19817747]  {CVE-2014-4653}     {CVE-2014-4654} {CVE-2014-4655}
    - kvm: iommu: fix the third parameter of kvm_iommu_put_pages (CVE-2014-3601) (Michael S. Tsirkin)     [Orabug: 19817646]  {CVE-2014-3601}
    - net: sctp: inherit auth_capable on INIT collisions (Daniel Borkmann)  [Orabug: 19816067]     {CVE-2014-5077}

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 Linux kernel's futex subsystem handled reference counting when requeuing futexes during futex_wait().
A local, unprivileged user could use this flaw to zero out the reference counter of an inode or an mm struct that backs up the memory area of the futex, which could lead to a use-after-free flaw, resulting in a system crash or, potentially, privilege escalation.
(CVE-2014-0205, Important)

* A NULL pointer dereference flaw was found in the way the Linux kernel's networking implementation handled logging while processing certain invalid packets coming in via a VxLAN interface. A remote attacker could use this flaw to crash the system by sending a specially crafted packet to such an interface. (CVE-2014-3535, Important)

* An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system.
(CVE-2014-3917, Moderate)

* An integer underflow flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation processed certain COOKIE_ECHO packets. By sending a specially crafted SCTP packet, a remote attacker could use this flaw to prevent legitimate connections to a particular SCTP server socket to be made.
(CVE-2014-4667, Moderate)

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

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

    - [kernel] futex: Fix errors in nested key ref-counting (Denys Vlasenko) [1094457 1094458] {CVE-2014-0205}

    - [kernel] auditsc: audit_krule mask accesses need bounds checking (Denys Vlasenko) [1102704 1102705]     {CVE-2014-3917}
    - [netdrv] pppol2tp: fail when socket option level is not SOL_PPPOL2TP [1119461 1119462] {CVE-2014-4943}
    - [kernel] utrace: force IRET path after utrace_finish_vfork() (Oleg Nesterov) [1115932 1115933]     {CVE-2014-4699}
    - [net] sctp: Fix sk_ack_backlog wrap-around problem (Daniel Borkmann) [1113969 1085932] {CVE-2014-4667}

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

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

Red Hat would like to thank Gopal Reddy Kodudula of Nokia Siemens Networks for reporting CVE-2014-4667. The security impact of the CVE-2014-0205 issue was discovered by Mateusz Guzik of Red Hat.

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

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 remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2014:1168 advisory.

    The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization     Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor     is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes     everything necessary to run and manage virtual machines: a subset of the     Red Hat Enterprise Linux operating environment and the Red Hat Enterprise     Virtualization Agent.

    Note: Red Hat Enterprise Virtualization Hypervisor is only available for     the Intel 64 and AMD64 architectures with virtualization extensions.

    A NULL pointer dereference flaw was found in the way the Linux kernel's     networking implementation handled logging while processing certain invalid     packets coming in via a VxLAN interface. A remote attacker could use this     flaw to crash the system by sending a specially crafted packet to such an     interface. (CVE-2014-3535)

    Two integer overflow flaws were found in the QEMU block driver for QCOW     version 1 disk images. A user able to alter the QEMU disk image files     loaded by a guest could use either of these flaws to corrupt QEMU process     memory on the host, which could potentially result in arbitrary code     execution on the host with the privileges of the QEMU process.
    (CVE-2014-0222, CVE-2014-0223)

    Red Hat would like to thank NSA for reporting CVE-2014-0222 and     CVE-2014-0223.

    This update also fixes the following bug:

    * Previously, an updated version of Qlogic firmware was not supported in     the Red Hat Enterprise Virtualization Hypervisor 6.5 image and an error     message returned when users were using a newer version of Qlogic firmware.
    This update includes the latest Qlogic firmware package in the Red Hat     Enterprise Virtualization Hypervisor 6.5 image so no firmware errors are     returned. (BZ#1135780)

    This updated package also provides updated components that include fixes     for various security issues. These issues have no security impact on Red     Hat Enterprise Virtualization Hypervisor itself, however. The security     fixes included in this update address the following CVE numbers:

    CVE-2012-6647, CVE-2013-7339, CVE-2014-2672, CVE-2014-2678, CVE-2014-2706,     CVE-2014-2851, CVE-2014-3144, CVE-2014-3145, CVE-2014-0205, CVE-2014-3917,     and CVE-2014-4667 (kernel issues)

    Users of the Red Hat Enterprise Virtualization Hypervisor are advised to     upgrade to this updated package.
