    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.
