The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-1304 advisory.

    - [net] rds: set correct msg_namelen (Weiping Pan) [822729 822731] {CVE-2012-3430}
    - [mm] hugetlb: fix resv_map leak in error path (Motohiro Kosaki) [824350 824351] {CVE-2012-2390}
    - [netdrv] dl2k: fix unfiltered netdev rio_ioctl access by users (Jacob Tanenbaum) [818824 818825]     {CVE-2012-2313}
    - [drm] i915: fix integer overflow in i915_gem_do_execbuffer() (Jacob Tanenbaum) [824561 824563]     {CVE-2012-2384}

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.

Andy Adamson discovered a flaw in the Linux kernel's NFSv4 implementation. A remote NFS server (attacker) could exploit this flaw to cause a denial of service. (CVE-2011-4131)

A flaw was discovered in the Linux kernel's KVM (kernel virtual machine). An administrative user in the guest OS could leverage this flaw to cause a denial of service in the host OS. (CVE-2012-2121)

Schacher Raindel discovered a flaw in the Linux kernel's memory handling when hugetlb is enabled. An unprivileged local attacker could exploit this flaw to cause a denial of service and potentially gain higher privileges. (CVE-2012-2133)

Stephan Mueller reported a flaw in the Linux kernel's dl2k network driver's handling of ioctls. An unprivileged local user could leverage this flaw to cause a denial of service. (CVE-2012-2313)

Timo Warns reported multiple flaws in the Linux kernel's hfsplus filesystem. An unprivileged local user could exploit these flaws to gain root system priviliges. (CVE-2012-2319)

Xi Wang discovered a flaw in the Linux kernel's i915 graphics driver handling of cliprect on 32 bit systems. An unprivileged local attacker could leverage this flaw to cause a denial of service or potentially gain root privileges. (CVE-2012-2383)

Xi Wang discovered a flaw in the Linux kernel's i915 graphics driver handling of buffer_count on 32 bit systems. An unprivileged local attacker could leverage this flaw to cause a denial of service or potentially gain root privileges. (CVE-2012-2384).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

The Red Hat Security Response Team has rated this update as having moderate 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.

This update fixes the following security issues :

* An integer overflow flaw was found in the i915_gem_do_execbuffer() function in the Intel i915 driver in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service.
This issue only affected 32-bit systems. (CVE-2012-2384, Moderate)

* A memory leak flaw was found in the way the Linux kernel's memory subsystem handled resource clean up in the mmap() failure path when the MAP_HUGETLB flag was set. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2390, Moderate)

* A race condition was found in the way access to inet->opt ip_options was synchronized in the Linux kernel's TCP/IP protocol suite implementation. Depending on the network facing applications running on the system, a remote attacker could possibly trigger this flaw to cause a denial of service. A local, unprivileged user could use this flaw to cause a denial of service regardless of the applications the system runs. (CVE-2012-3552, Moderate)

* A flaw was found in the way the Linux kernel's dl2k driver, used by certain D-Link Gigabit Ethernet adapters, restricted IOCTLs. A local, unprivileged user could use this flaw to issue potentially harmful IOCTLs, which could cause Ethernet adapters using the dl2k driver to malfunction (for example, losing network connectivity).
(CVE-2012-2313, Low)

* A flaw was found in the way the msg_namelen variable in the rds_recvmsg() function of the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation was initialized. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space.
(CVE-2012-3430, Low)

Red Hat would like to thank Hafid Lin for reporting CVE-2012-3552, and Stephan Mueller for reporting CVE-2012-2313. The CVE-2012-3430 issue was discovered by the Red Hat InfiniBand team.

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.

Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect.
