                     CVE-2012-3531
    
    Several vulnerabilities were discovered in TYPO3, a content management
    system.
    
    CVE-2012-3527
    	An insecure call to unserialize in the help system enables
    	arbitrary code execution by authenticated users.
    
    CVE-2012-3528
    	The TYPO3 backend contains several cross-site scripting
    	vulnerabilities.
    
    CVE-2012-3529
    	Authenticated users who can access the configuration module
    	can obtain the encryption key, allowing them to escalate their
    	privileges.
    
    CVE-2012-3530
    	The RemoveXSS HTML sanitizer did not remove several HTML5
    	JavaScript, thus failing to mitigate the impact of cross-site
    	scripting vulnerabilities.
    
    For the stable distribution (squeeze), these problems have been fixed
    in version 4.3.9+dfsg1-1+squeeze5.
    
    For the testing distribution (wheezy) and the unstable distribution
    (sid), these problems have been fixed in version 4.5.19+dfsg1-1.
    
    We recommend that you upgrade your typo3-src packages.
