DESCRIPTION:
KeyShore and Yog have discovered a vulnerability in iCal, which can
be exploited by malicious people to conduct script insertion
attacks.

Input passed to the "Calendar Text" field when adding a new event
isn't properly sanitised before being used. This can be exploited to
inject arbitrary HTML and script code, which will be executed in a
user's browser session in context of an affected site when the
malicious user data is viewed.

The vulnerability has been confirmed in version 3.10. Other versions
may also be affected.

SOLUTION:
Edit the configuration so that only trusted users can add new events.
