DESCRIPTION:
A vulnerability has been reported in the Block Class module for
Drupal, which can be exploited by malicious users to conduct script
insertion attacks.

Input passed via the class name when adding or modifying a class in a
block is not properly sanitised before being used. 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 permission to modify or create
blocks.

The vulnerability is reported in versions prior to 7.x-1.0.

SOLUTION:
Update to version 7.x-1.1.
