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 38f2e3a0-b61e-11ec-9ebc-1c697aa5a594 advisory.

 - zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. (CVE-2018-25032)

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