Updated fam packages that fix an information disclosure bug are now available.

3. Problem description:

FAM, the File Alteration Monitor, provides a daemon and an API which applications can use for notification of changes in specific files or directories.

A bug has been found in the way FAM handles group permissions. It is possible that a local unprivileged user can use a flaw in FAM's group handling to discover the names of files which are only viewable to users in the 'root' group. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-0875 to this issue. This issue only affects the version of FAM shipped with Red Hat Enterprise Linux 2.1.

Users of FAM should update to these updated packages which contain backported patches and are not vulnerable to this issue.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:
