Debian DLA-1216-1 : wordpress security update

high Nessus Plugin ID 105423


The remote Debian host is missing a security update.


Several vulnerabilities were discovered in wordpress, a web blogging tool. The Common Vulnerabilities and Exposures project identifies the following issues.


wp-admin/user-new.php in WordPress sets the newbloguser key to a string that can be directly derived from the user ID, which allows remote attackers to bypass intended access restrictions by entering this string.


wp-includes/functions.php in WordPress does not require the unfiltered_html capability for upload of .js files, which might allow remote attackers to conduct XSS attacks via a crafted file.


wp-includes/general-template.php in WordPress does not properly restrict the lang attribute of an HTML element, which might allow attackers to conduct XSS attacks via the language setting of a site.


wp-includes/feed.php in WordPress does not properly restrict enclosures in RSS and Atom fields, which might allow attackers to conduct XSS attacks via a crafted URL.

For Debian 7 'Wheezy', these problems have been fixed in version 3.6.1+dfsg-1~deb7u20.

We recommend that you upgrade your wordpress packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected wordpress, and wordpress-l10n packages.
