Multiple vulnerabilities have been reported in Joomla!, which can be
exploited by malicious people to conduct cross-site scripting
attacks, disclose sensitive information, and bypass certain security
restrictions.

1) 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.

2) Certain unspecified improper error checks can be exploited to
disclose certain information.

3) Certain improper permission checks can be exploited to gain
unauthorised access.

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.

The vulnerabilities are reported in versions 1.6.3 and prior.

SOLUTION:
Update to version 1.6.4.
