Updated wordpress and php-phpmailer packages fix security vulnerabilities
wp-includes/functions.php in WordPress before 3.6.1 does not properly determine whether data has been serialized, which allows remote attackers to execute arbitrary code by triggering erroneous PHP unserialize operations (CVE-2013-4338).
WordPress before 3.6.1 does not properly validate URLs before use in an HTTP redirect, which allows remote attackers to bypass intended redirection restrictions via a crafted string (CVE-2013-4339).
wp-admin/includes/post.php in WordPress before 3.6.1 allows remote authenticated users to spoof the authorship of a post by leveraging the Author role and providing a modified user_ID parameter (CVE-2013-4340).
The get_allowed_mime_types function in wp-includes/functions.php in WordPress before 3.6.1 does not require the unfiltered_html capability for uploads of .htm and .html files, which might make it easier for remote authenticated users to conduct cross-site scripting (XSS) attacks via a crafted file (CVE-2013-5738).
The default configuration of WordPress before 3.6.1 does not prevent uploads of .swf and .exe files, which might make it easier for remote authenticated users to conduct cross-site scripting (XSS) attacks via a crafted file, related to the get_allowed_mime_types function in wp-includes/functions.php (CVE-2013-5739).
Additionally, php-phpmailer has been updated to a newer version required by the updated wordpress.
