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 187ab98e-2953-4495-b379-4060bd4b75ee advisory.

 - Python Packaging Authority (PyPA) setuptools before 65.5.1 allows remote attackers to cause a denial of service via HTML in a crafted package or custom PackageIndex page. There is a Regular Expression Denial of Service (ReDoS) in package_index.py. (CVE-2022-40897)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
