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.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002223 advisory.

    arch/x86/kernel/cpu/perf_event_intel.c in the Linux kernel before 3.8.9, when the Performance Events     Subsystem is enabled, specifies an incorrect bitmask, which allows local users to cause a denial of     service (general protection fault and system crash) by attempting to set a reserved bit.

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.

The Red Hat Security Response Team 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.

This update fixes the following security issues :

* A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled duplicate cookies.
If a local user queried SCTP connection information at the same time a remote attacker has initialized a crafted SCTP connection to the system, it could trigger a NULL pointer dereference, causing the system to crash. (CVE-2013-2206, Important)

* It was found that the fix for CVE-2012-3552 released via RHSA-2012:1304 introduced an invalid free flaw in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to corrupt kernel memory via crafted sendmsg() calls, allowing them to cause a denial of service or, potentially, escalate their privileges on the system. (CVE-2013-2224, Important)

* A flaw was found in the Linux kernel's Performance Events implementation. On systems with certain Intel processors, a local, unprivileged user could use this flaw to cause a denial of service by leveraging the perf subsystem to write into the reserved bits of the OFFCORE_RSP_0 and OFFCORE_RSP_1 model-specific registers.
(CVE-2013-2146, Moderate)

* An invalid pointer dereference flaw was found in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system by using sendmsg() with an IPv6 socket connected to an IPv4 destination. (CVE-2013-2232, Moderate)

* Information leak flaws in the Linux kernel's Bluetooth implementation could allow a local, unprivileged user to leak kernel memory to user-space. (CVE-2012-6544, Low)

* An information leak flaw in the Linux kernel could allow a privileged, local user to leak kernel memory to user-space.
(CVE-2013-2237, Low)

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