DESCRIPTION:
Jose Luis Góngora Fernández has discovered a vulnerability in
PHPSlideshow, which can be exploited by malicious people to conduct
cross-site scripting attacks.

Input passed to the "directory" parameter in phpslideshow.php is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

The vulnerability is confirmed in version 0.9.9.2. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
