Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-1622 CVE-2007-1893 CVE-2007-1894 CVE-2007-1897

CVE-2007-1622
     Cross-site scripting (XSS) vulnerability in wp-admin/vars.php in
     WordPress before 2.0.10 RC2, and before 2.1.3 RC2 in the 2.1 series,
     allows remote authenticated users with theme privileges to inject
     arbitrary web script or HTML via the PATH_INFO in the administration
     interface, related to loose regular expression processing of PHP_SELF.

CVE-2007-1893
     WordPress 2.1.2, and probably earlier, allows remote authenticated
     users with the contributor role to bypass intended access restrictions
     and invoke the publish_posts functionality, which can be used to
     "publish a previously saved post."

CVE-2007-1894
     Cross-site scripting (XSS) vulnerability in
     wp-includes/general-template.php in WordPress before 20070309 allows
     remote attackers to inject arbitrary web script or HTML via the year
     parameter in the wp_title function.

CVE-2007-1897
     SQL injection vulnerability in xmlrpc.php in WordPress 2.1.2, and
     probably earlier, allows remote authenticated users to execute
     arbitrary SQL commands via a string parameter value in an XML RPC
     mt.setPostCategories method call, related to the post_id variable.

For the stable distribution (etch) these issues have been fixed in
version 2.0.10-1.

For the testing and unstable distributions (lenny and etch,
respectively), these issues have been fixed in version 2.1.3-1

We recommend that you upgrade your wordpress package.
