DESCRIPTION:
Some vulnerabilities have been reported in Serendipity, which can be
exploited by malicious people to bypass certain security restrictions
and conduct cross-site scripting attacks.

1) An error in the file upload handling can be exploited by authors
to upload certain special files without privileges.

2) Input passed to the "templatedropdown" and "shoutbox" plugins
isn't 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 vulnerabilities have been reported in version 0.8. Prior versions
may also be affected.

SOLUTION:
Update to version 0.8.1.
http://sourceforge.net/project/shownotes.php?release_id=328092
