Alpine: libcrypto3, multiple openssl packages: security update to 3.1.1-r1 (deprecated)

medium Tenable Cloud Security Plugin ID 400089

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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 misled 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. (CVE-2023-2975)
