Debian: Security update for Typo3

Several remote vulnerabilities have been discovered in the TYPO3 web content management framework. Failing to properly HTML-encode user input in several places, the TYPO3 backend is susceptible to Cross-Site Scripting. A valid backend user is required to exploit these vulnerabilities. Accessing a CLI Script directly with a browser may disclose the database name used for the TYPO3 installation.

By not removing non printable characters, the API method t3lib_div::RemoveXSS() fails to filter specially crafted HTML injections, thus is susceptible to Cross-Site Scripting.

Updated packages are available from security.debian.org.
