DESCRIPTION:
A security issue and a vulnerability have been reported in Joomla!,
which can be exploited by malicious people to disclose potentially
sensitive information and conduct cross-site scripting attacks.

exploited to disclose certain information from the administration
backend.
2) Certain input passed via the update manager 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 security issue and vulnerability are reported in versions prior
to 2.5.4.
SOLUTION:
Update to version 2.5.4.
