High Nessus Plugin ID 67595

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

From Red Hat Security Advisory 2007:0993 :

Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 5 kernel are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the following security issues :

A memory leak was found in the Red Hat Content Accelerator kernel patch. A local user could use this flaw to cause a denial of service (memory exhaustion). (CVE-2007-5494, Important)

A flaw was found in the handling of IEEE 802.11 frames affecting several wireless LAN modules. In certain circumstances, a remote attacker could trigger this flaw by sending a malicious packet over a wireless network and cause a denial of service (kernel crash).
(CVE-2007-4997, Important).

A flaw was found in the Advanced Linux Sound Architecture (ALSA). A local user who had the ability to read the /proc/driver/snd-page-alloc file could see portions of kernel memory. (CVE-2007-4571, Moderate).

In addition to the security issues described above, several bug fixes preventing possible memory corruption, system crashes, SCSI I/O fails, networking drivers performance regression and journaling block device layer issue were also included.

Red Hat Enterprise Linux 5 users are advised to upgrade to these packages, which contain backported patches to resolve these issues.

Red Hat would like to credit Vasily Averin, Chris Evans, and Neil Kettle for reporting the security issues corrected by this update.

Solution

Update the affected kernel packages.
