The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the dc49f6dc-99d2-11ed-86e9-d4c9ef517024 advisory.

  - A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including     3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including     3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can lead to out of memory failures.
    A specially crafted message with multiple key-value per elements creates parsing issues, and can lead to a     Denial of Service against services receiving unsanitized input. We recommend upgrading to versions 3.18.3,     3.19.5, 3.20.2, 3.21.6 for protobuf-cpp and 3.18.3, 3.19.5, 3.20.2, 4.21.6 for protobuf-python. Versions     for 3.16 and 3.17 are no longer updated. (CVE-2022-1941)

  - In Cyrus SASL 2.1.17 through 2.1.27 before 2.1.28, plugins/sql.c does not escape the password for a SQL     INSERT or UPDATE statement. (CVE-2022-24407)

  - A parsing issue with binary data in protobuf-java core and lite versions prior to 3.21.7, 3.20.3, 3.19.6     and 3.16.3 can lead to a denial of service attack. Inputs containing multiple instances of non-repeated     embedded messages with repeated or unknown fields causes objects to be converted back-n-forth between     mutable and immutable forms, resulting in potentially long garbage collection pauses. We recommend     updating to the versions mentioned above. (CVE-2022-3171)

  - When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to     ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle     previously was used to issue a `PUT` request which used that callback. This flaw may surprise the     application and cause it to misbehave and either send off the wrong data or use memory after free or     similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is     changed from a PUT to a POST. (CVE-2022-32221)
