Description

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.

For the stable distribution (squeeze), these problems have been fixed in version 4.3.9+dfsg1-1+squeeze3.

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.
