Several vulnerabilities were discovered in wordpress, a web blogging tool. The Common Vulnerabilities and Exposures project identifies the following issues.
Cross-site scripting (XSS) vulnerability in wp-includes/wp-db.php in 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
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.
The oEmbed protocol implementation in WordPress before 4.5.3 allows remote attackers to cause a denial of service via unspecified vectors.
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.
Cross-site request forgery (CSRF) vulnerability in the wp_ajax_wp_compression_test function in wp-admin/includes/ajaxactions.php in WordPress before 4.5 allows remote attackers to hijack the authentication of administrators for requests that change the script compression option.
Fix a cross-site scripting vulnerability via image filename.
Fix a path traversal vulnerability in the upgrade package uploader.
For Debian 7
Wheezy, these problems have been fixed in version 3.6.1+dfsg-1~deb7u12.
We recommend that you upgrade your wordpress packages.
