RHEL 2.1 : kernel (RHSA-2004:354)

low Nessus Plugin ID 12510

Synopsis

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

Description

Updated kernel packages that fix a security vulnerability affecting the kernel nfs server for Red Hat Enterprise Linux 2.1 are now available.

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

During an audit of the Linux kernel, SUSE discovered a flaw that allowed a user to make unauthorized changes to the group ID of files in certain circumstances. In the 2.4 kernel, as shipped with Red Hat Enterprise Linux, the only way this could happen is through the kernel nfs server. A user on a system that mounted a remote file system from a vulnerable machine may be able to make unauthorized changes to the group ID of exported files. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0497 to this issue.

Only Red Hat Enterprise Linux systems that are configured to share file systems via NFS are affected by this issue.

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum. These packages contain a backported patch to correct this issue.

Solution

Update the affected packages.
