Several remote vulnerabilities have been discovered in the TYPO3 web content management framework: CVE-2012-1606 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. CVE-2012-1607 Accessing a CLI Script directly with a browser may disclose the database name used for the TYPO3 installation. CVE-2012-1608 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.

For the testing distribution (wheezy) and the unstable distribution (sid), these problems have been fixed in version 4.5.14+dfsg1-1. We recommend that you upgrade your typo3-src packages.
