DESCRIPTION:
A security issue and a vulnerability have been reported in the
Organic Groups module for Drupal, which can be exploited by malicious
users to conduct script insertion attacks and by malicious people to
bypass certain security restrictions.

1) An error due to the module not properly verifying the "access
content" permission can be exploited to gain access to otherwise
restricted content.

Successful exploitation of this vulnerability requires that all users
have the "access content" permissions removed.

2) Certain input when creating or editing a group title 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 of this vulnerability requires the Vertical
Tabs module to be installed, the Vertical Tabs configuration to
include the Organic Group select area, and the permissions to create
or edit a group title.

The security issue and vulnerability are reported in 6.x-2.x versions
prior to 6.x-2.4.

SOLUTION:
Update to version 6.x-2.4.
