    Package : wordpress
    Vulnerability : several
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2013-4338 CVE-2013-4339 CVE-2013-4340 CVE-2013-5738
    CVE-2013-5739
    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.
