Vulnerabilities > CVE-2023-6918 - Unchecked Return Value vulnerability in multiple products

Summary

A flaw was found in the libssh implements abstract layer for message digest (MD) operations implemented by different supported crypto backends.

In this case, non-matching keys will result in decryption/integrity failures, terminating the connection.
