The remote host is missing updates announced in
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.

Red Hat Network. To use Red Hat Network, launch the Red
