DESCRIPTION:
Aliaksandr Hartsuyeu has reported two vulnerabilities in PHP
iCalendar, which can be exploited by malicious people to compromise a
vulnerable system.

Input passed to the "file" parameter in "functions/template.php" and
the "getdate" parameter in "search.php" isn't properly verified,
before it is used to include files. This can be exploited to include
arbitrary files from external and local resources.

The vulnerabilities have been reported in versions 2.0.1, 2.1, and
2.2. Other versions may also be affected.
