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

CVE-2015-8834:

WordPress before 4.2.2 allows remote attackers to inject arbitrary
web script or HTML via a long comment that is improperly stored
because of limitations on the MySQL TEXT data type.
NOTE: this vulnerability exists because of an incomplete fix for
CVE-2015-3440

CVE-2016-4029:
WordPress before 4.5 does not consider octal and hexadecimal IP
address formats when determining an intranet address, which allows
remote attackers to bypass an intended SSRF protection mechanism
via a crafted address.

CVE-2016-5836:
The oEmbed protocol implementation in WordPress before 4.5.3 allows
remote attackers to cause a denial of service via unspecified
vectors.

CVE-2016-6634:
Cross-site scripting (XSS) vulnerability in the network settings
page in WordPress before 4.5 allows remote attackers to inject
arbitrary web script or HTML via unspecified vectors.

CVE-2016-6635:
Cross-site request forgery (CSRF) vulnerability in the
wp_ajax_wp_compression_test function in wp-admin/includes/ajax-
actions.php in WordPress before 4.5 allows remote attackers to
hijack the authentication of administrators for requests that
change the script compression option.

CVE-2016-7168:
Fix a cross-site scripting vulnerability via image filename.

CVE-2016-7169:
Fix a path traversal vulnerability in the upgrade package uploader.

For Debian 7 "Wheezy", these problems have been fixed in version
