Joomla! Multiple Vulnerabilities

Two vulnerabilities have been identified in Joomla!, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.

1. Certain input passed to the Highlight plugin 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 input passed to the Redirect plugin is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
