FreeBSD : liboqs -- Correctness error in HQC decapsulation (dc087dad-bd71-11ef-b5a1-000ec6d40964)

high Nessus Plugin ID 213243

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 dc087dad-bd71-11ef-b5a1-000ec6d40964 advisory.

The Open Quantum Safe project reports:
A correctness error has been identified in the reference implementation of the HQC key encapsulation mechanism. Due to an indexing error, part of the secret key is incorrectly treated as non-secret data.
This results in an incorrect shared secret value being returned when the decapsulation function is called with a malformed ciphertext.
No concrete attack exploiting the error has been identified at this point. However, the error involves mishandling of the secret key, and in principle this presents a security vulnerability.

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.
