Debian: New webcalendar packages fix information leak

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. Fixed packages are available from security.debian.org.

Debian-specific: no
CVE ID         : CVE-2006-2247
Debian Bug     : 366927

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.
