CWE-200  (opens in a new tab)

How to fix?

Upgrade Debian:9 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:9 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.
