DESCRIPTION:
Multiple vulnerabilities have been reported in Joomla!, which can be
exploited by malicious users to bypass certain security restrictions
and cause a DoS (Denial of Service) and by malicious people to
disclose sensitive information, conduct cross-site scripting and
request forgery, and SQL injection attacks.

1) Certain unspecified input is not properly sanitised before being
used. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

NOTE: This can further be exploited to disclose the installation path
via SQL error messages.

2) Certain unhandled exceptions can be exploited to disclose the full
installation path.

3) Certain double URL-encoded input is not 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.

4) Certain unspecified input is not 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.

5) An error in the checking of access permissions can be exploited to
disclose certain information.

6) Certain unspecified input is not properly verified before being
used to redirect users. This can be exploited to redirect a user to
an arbitrary site e.g. when the user clicks a specially crafted link
to the affected script hosted on a trusted domain.

7) Certain unspecified input is not properly sanitised before being
used. This can be exploited to disclose potentially sensitive
information.

8) An error in the handling of access permissions can be exploited to
edit otherwise restricted files.

9) The application allows users to perform certain actions via HTTP
requests without making proper validity checks to verify the
requests. This can be exploited to perform certain unspecified
actions within the application by tricking a user into visiting a
malicious web site while being logged in to the application.

10) An error within the editor caching facility can be exploited to
use all available disk space.

The vulnerabilities are reported in versions prior to 1.6.1.

SOLUTION:
Update to version 1.6.1.

PROVIDED AND/OR DISCOVERED BY:
