Security update: TYPO3 content management framework

Several remote vulnerabilities have been discovered in the TYPO3 content management framework.

Because of a not sufficiently secure default value of the TYPO3 configuration variable fileDenyPattern, authenticated backend users could upload files that allowed to execute arbitrary code as the webserver user.

User input processed by fe_adminlib.inc is not being properly filtered to prevent Cross Site Scripting (XSS) attacks, which is exposed when specific plugins are in use.
