DESCRIPTION:
A vulnerability has been reported in ikiwiki, which can be exploited
by malicious users to conduct script insertion attacks.

Input passed via the "meta stylesheet" directive is not properly
sanitised before being used as an alternate stylesheet. This can be
exploited to insert arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
when the malicious data is being viewed.

Successful exploitation requires permissions to upload stylesheets.

The vulnerability is reported in versions prior to 3.20110328.

SOLUTION:
Update to version 3.20110328.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Giuseppe Bilotta.
