RHEL 4 : kernel (RHSA-2007:0085)

medium Nessus Plugin ID 24724

Synopsis

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

Description

Updated kernel packages that fix two security issues and a bug in the Red Hat Enterprise Linux 4 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 two security issues :

* a flaw in the key serial number collision avoidance algorithm of the keyctl subsystem that allowed a local user to cause a denial of service (CVE-2007-0006, Important)

* a flaw in the file watch implementation of the audit subsystems that allowed a local user to cause a denial of service (panic). To exploit this flaw a privileged user must have previously created a watch for a file (CVE-2007-0001, Moderate)

In addition to the security issues described above, a fix for the SCTP subsystem to address a system crash which may be experienced in Telco environments has been included.

Red Hat Enterprise Linux 4 users are advised to upgrade their kernels to the packages associated with their machine architecture and configurations as listed in this erratum.

Solution

Update the affected packages.
