Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the de970aef-d60e-466b-8e30-1ae945a047f1 advisory.

 - 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. (CVE-2023-26112)
