DESCRIPTION:
A weakness, a security issue, and multiple vulnerabilities have been
reported in Drupal, which can be exploited by malicious users to
disclose sensitive information, bypass certain security restrictions,
and cause a DoS (Denial of Service).

1) A weakness is caused due to inefficient text matching pattern and
can be exploited to exhaust memory or cause a high CPU load via
specially crafted strings passed to the filter system e.g. when
posting comments or forum topics.

2) An error due to the application not properly validating the
destination for submitted forms can be exploited to redirect
submission of sensitive data (e.g. login credentials) to a malicious
website.

3) An error due to the application not properly validating user
permissions when displaying the forum overview page can be exploited
to expose certain metadata of unpublished forum posts.

4) An error due to the application not properly validating user
access to cached derivatives of users' private images can be
exploited to gain access to derivatives of otherwise restricted
images.

5) An error due to the application not properly validating user
access to each node in the list of nodes can be exploited to gain
access to otherwise restricted nodes.

Successful exploitation of this vulnerability requires the "view
content overview" permission and a contributed node access module.

The vulnerabilities are reported in 7.x versions prior to 7.13.

SOLUTION:
Update to version 7.13.

PROVIDED AND/OR DISCOVERED BY:
2) Reported by the vendor.

1) Jay Wineinger and Lin Clark
