DESCRIPTION:
Keigo Yamazaki has reported some vulnerabilities in Xoops, which can
be exploited by malicious people to conduct script insertion
attacks.

1) Input passed to certain "XOOPS Code" tags 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.

2) Certain input passed to the "newbb" forum module 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
when the user views a submitted forum message.

The vulnerabilities have been reported in the following versions:
* Xoops 2.0.12 JP and prior.
* Xoops 2.0.13.1 and prior.
* Xoops 2.2.3 RC1 and prior.
