RHEL 6 : kernel-rt (RHSA-2012:1282)

medium Nessus Plugin ID 76652

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:1282 advisory.

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

This update fixes the following security issue:

* It was found that a deadlock could occur in the Out of Memory (OOM) killer. A process could trigger this deadlock by consuming a large amount of memory, and then causing request_module() to be called. A local, unprivileged user could use this flaw to cause a denial of service (excessive memory consumption). (CVE-2012-4398, Moderate)

Red Hat would like to thank Tetsuo Handa for reporting this issue.

The kernel-rt packages have been upgraded to upstream version 3.2, which provides a number of bug fixes and enhancements over the previous version.
(BZ#798421)

This update also fixes various bugs and adds enhancements. 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 kernel-rt packages, which correct this issue, fix these bugs, and add these enhancements. 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.

Solution

Update the affected packages.
