Red Hat Enterprise Linux 5 RHSA-2012-1174-01 Low: Network Driver Threat

Red Hat recommends a minor kernel upgrade addressing a security vulnerability along with various bug fixes in RHEL 5. Users are encouraged to update.
Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 5

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258

To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.

Summary

The kernel packages contain the Linux kernel, the core of any Linux operating system.
This update fixes the following security issue:
* 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)
Red Hat would like to thank Stephan Mueller for reporting this issue.
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.
