Updated wordpress package fixes security vulnerabilities
A denial of service flaw was found in the way Wordpress, a blog tool and publishing platform, performed hash computation when checking password for password protected blog posts. A remote attacker could provide a specially- crafted input that, when processed by the password checking mechanism of Wordpress would lead to excessive CPU consumption (CVE-2013-2173).
Inadequate SSRF protection for HTTP requests where the user can provide a URL can allow for attacks against the intranet and other sites. This is a continuation of work related to CVE-2013-0235, which was specific to SSRF in pingback requests and was fixed in 3.5.1 (CVE-2013-2199).
Inadequate checking of a user's capabilities could allow them to publish posts when their user role should not allow for it; and to assign posts to other authors (CVE-2013-2200).
Inadequate escaping allowed an administrator to trigger a cross-site scripting vulnerability through the uploading of media files and plugins (CVE-2013-2201).
The processing of an oEmbed response is vulnerable to an XXE (CVE-2013-2202).
If the uploads directory is not writable, error message data returned via XHR will include a full path to the directory (CVE-2013-2203).
Content Spoofing in the MoxieCode (TinyMCE) MoxiePlayer project (CVE-2013-2204).
Cross-domain XSS in SWFUpload (CVE-2013-2205).
