More information:

David Maciejak noticed that webcalendar, a PHP-based multi-user calendar, returns different error messages on login attempts for an invalid password and a non-existing user, allowing remote attackers to gain information about valid usernames.

The old stable distribution (woody) does not contain a webcalendar package.

For the stable distribution (sarge) this problem has been fixed in version 0.9.45-4sarge4.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your webcalendar package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
