Debian DSA-2757-1 : wordpress - several vulnerabilities

high Nessus Plugin ID 69895

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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).

Solution

Upgrade the wordpress packages.

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.
