RHSA-2005:005 - Security Advisory

Topic

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

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.
