CVSS: 5.3EPSS: 0%CPEs: 4EXPL: 0CVE-2023-2975 – AES-SIV implementation ignores empty associated data entries
https://notcve.org/view.php?id=CVE-2023-2975
Issue summary: The AES-SIV cipher implementation contains a bug that causes it to ignore empty associated data entries which are unauthenticated as a consequence. Impact summary: Applications that use the AES-SIV algorithm and want to authenticate empty data entries as associated data can be mislead by removing adding or reordering such empty entries as these are ignored by the OpenSSL implementation. We are currently unaware of any such applications. The AES-SIV algorithm allows for authentication of multiple associated data entries along with the encryption. To authenticate empty data the application has to call EVP_EncryptUpdate() (or EVP_CipherUpdate()) with NULL pointer as the output buffer and 0 as the input buffer length. The AES-SIV implementation in OpenSSL just returns success for such a call instead of performing the associated data authentication operation. The empty data thus will not be authenticated. As this issue does not affect non-empty associated data authentication and we expect it to be rare for an application to use empty associated data entries this is qualified as Low severity issue.

https://notcve.org/view.php?id=CVE-2022-38023
Netlogon RPC Elevation of Privilege Vulnerability Vulnerabilidad de elevación de privilegios de Netlogon RPC A flaw was found in samba. The Netlogon RPC implementations may use the rc4-hmac encryption algorithm, which is considered weak and should be avoided even if the client supports more modern encryption types. This issue could allow an attacker who knows the plain text content communicated between the samba client and server to craft data with the same MD5 calculation and replace it without being detected. • https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-38023 https://security.gentoo.org/glsa/202309-06 https://access.redhat.com/security/cve/CVE-2022-38023 https://bugzilla.redhat.com/show_bug.cgi?id=2154362 • CWE-328: Use of Weak Hash •
