CVE-2015-5730 Open this link in a new tabHow to fix?
Upgrade Debian:unstable wordpress to version 4.2.4+dfsg-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wordpress package and not the wordpress package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
The sanitize_widget_instance function in wp-includes/class-wp-customize-widgets.php in WordPress before 4.2.4 does not use a constant-time comparison for widgets, which allows remote attackers to conduct a timing side-channel attack by measuring the delay before inequality is calculated.
