A vulnerability was found in Red Hat Ceph Storage 4 and Red Hat Openshift Container Storage 4.2 where, A nonce reuse vulnerability was discovered in the secure mode of the messenger v2 protocol, which can allow an attacker to forge auth tags and potentially manipulate the data by leveraging the reuse of a nonce in a session. Messages encrypted using a reused nonce value are susceptible to serious confidentiality and integrity attacks. Se detectó una vulnerabilidad en Red Hat Ceph Storage versión 4 y Red Hat Openshift Container Storage versión 4.2 donde, se detectó una vulnerabilidad de reutilización de nonce en el modo seguro del protocolo de messenger v2, que puede permitir a un atacante falsificar etiquetas de autenticación y potencialmente manipular los datos al aprovechar la reutilización de un nonce en una sesión. Los mensajes cifrados usando un valor nonce reutilizado, son susceptibles de serios ataques de confidencialidad e integridad. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1759 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/P3A2UFR5IUIEXJUCF64GQ5OVLCZGODXE https://security.gentoo.org/glsa/202105-39 • CWE-323: Reusing a Nonce, Key Pair in Encryption CWE-330: Use of Insufficiently Random Values •

https://notcve.org/view.php?id=CVE-2020-1730
A flaw was found in libssh versions before 0.8.9 and before 0.9.4 in the way it handled AES-CTR (or DES ciphers if enabled) ciphers. The server or client could crash when the connection hasn't been fully initialized and the system tries to cleanup the ciphers when closing the connection. The biggest threat from this vulnerability is system availability. Se detectó un fallo en libssh versiones anteriores a 0.8.9 y versiones anteriores a 0.9.4, en la manera en que se manejaron los cifrados AES-CTR (o DES si está habilitado). El servidor o el cliente podrían bloquearse cuando la conexión no ha sido inicializada completamente y el sistema intenta limpiar los cifrados cuando se cierra la conexión. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1730 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2A7BIFKUYIYKTY7FX4BEWVC2OHS5DPOU https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VLSWHBQ3EPKGTGLQNH554Z746BJ3C554 https://security.netapp.com/advisory/ntap-20200424-0001 https://usn.ubuntu.com/4327-1 https://www.libssh.org/security/advisories/CVE-2020-1730.txt https://www.oracle.com/security-alerts/cpuoct2020.html https:/ • CWE-476: NULL Pointer Dereference •
