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 2ce1a2f1-0177-11ef-a45e-08002784c58d advisory.

 - sp2ip reports: If attacker-supplied data is provided to the Ruby regex compiler, it is possible to extract arbitrary heap data relative to the start of the text, including pointers and sensitive strings. (CVE-2024-27282)

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