How to fix?

Upgrade Debian:unstable configobj to version 5.0.8-2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream configobj package and not the configobj package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

All versions of the package configobj are vulnerable to Regular Expression Denial of Service (ReDoS) via the validate function, using (.+?)((.*)).

Note: This is only exploitable in the case of a developer, putting the offending value in a server side configuration file.
