RELEASE DATE:

DESCRIPTION:
Some vulnerabilities have been reported in the  RSForm! component for
Joomla!, which can be exploited by malicious people to disclose
sensitive information and conduct SQL injection attacks.

1) Input passed via the "lang" parameter to index.php (when "option"
is set to "com_forme") is not properly verified before being used to
include files. This can be exploited to include arbitrary files from
local resources via directory traversal sequences and URL-encoded
NULL bytes.

2) Input passed via the "lang" parameter to index.php (when "option"
is set to "com_forme") is not properly sanitised before being used in
SQL queries. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code.

The vulnerabilities are reported in version 1.0.5. Other versions may
also be affected.

SOLUTION:
Update to version 1.0.6.
