Package        : webcalendar
Vulnerability  : uninitialised variable
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2006-2762

A vulnerability has been discovered in webcalendar, a PHP-based
multi-user calendar, that allows a remote attacker to execute
arbitrary PHP code when register_globals is turned on.

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

For the stable distribution (sarge) this problem has been fixed in
version 0.9.45-4sarge5.

For the unstable distribution (sid) this problem has been fixed in
version 1.0.4-1

We recommend that you upgrade your webcalendar package.
