    Debian Bug     : 722537
    
    Several vulnerabilities were identified in Wordpress, a web blogging
    tool. As the CVEs were allocated from releases announcements and specific
    fixes are usually not identified, it has been decided to upgrade the
    Wordpress package to the latest upstream version instead of backporting
    the patches.
    
    This means extra care should be taken when upgrading, especially when
    using third-party plugins or themes, since compatibility may have been
    impacted along the way.  We recommend that users check their install
    before doing the upgrade.
    
    CVE-2013-4338
    
        Unsafe PHP unserialization in wp-includes/functions.php could cause
        arbitrary code execution.
    
    CVE-2013-4339
    
        Insufficient input validation could result in redirecting or leading
        a user to another website.
    
    CVE-2013-4340
    
        Privilege escalation allowing an user with an author role to create
        an entry appearing as written by another user.
    
    CVE-2013-5738
    
        Insufficient capabilities were required for uploading .html/.html
        files, making it easier for authenticated users to conduct cross-site
        scripting attacks (XSS) using crafted html file uploads.
    
    CVE-2013-5739
    
        Default Wordpress configuration allowed file upload for .swf/.exe
        files, making it easier for authenticated users to conduct cross-site
        scripting attacks (XSS).
    
    For the oldstable distribution (squeeze), these problems have been fixed in
    version 3.6.1+dfsg-1~deb6u1.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 3.6.1+dfsg-1~deb7u1.
    
    For the testing distribution (jessie), these problems have been fixed in
    version 3.6.1+dfsg-1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 3.6.1+dfsg-1.
    
    We recommend that you upgrade your wordpress packages.
