DESCRIPTION:
Some vulnerabilities have been reported in Joomla!, where some have
unknown impacts, and others can be exploited by malicious people to
conduct cross-site scripting attacks and bypass certain security
restrictions.

1) Some input validation errors exists in the "mosMail()" and
"JosIsValidEmail()" functions.

2) An unspecified error exists in PEAR.php.

3) An unspecified error exists due to globals.php not being included
in administrator/index.php.

4) Insufficient access control checks exists due to missing defined(
'_VALID_MOS' ) checks and certain errors in the Admin "Upload Image",
Admin "Popups",  and "com_content"  functionalities.

5) Certain unspecified errors in the "do_pdf" functionality and in
the handling of the emailform com_content task can be exploited to
bypass the user authentication process.

6) Some unspecified input passed via the Admin "Module Manager",
Admin "Help", and Search functionalities isn't 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.
