FreeBSD : OpenSSL -- key agreement vulnerability (ee1e6a24-1eeb-11f1-81da-8447094a420f)

critical Nessus Plugin ID 302192

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 ee1e6a24-1eeb-11f1-81da-8447094a420f advisory.

The OpenSSL project reports:
TLS 1.3 server may choose unexpected key agreement group (Low) An OpenSSL TLS 1.3 server may fail to negotiate the expected preferred key exchange group when its key exchange group configuration includes the default by using the DEFAULT keyword.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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

Solution

Update the affected packages.
