Libssh: missing checks for return values for digests
概要
Libssh: missing checks for return values for digests
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
A flaw was found in the libssh implements abstract layer for message digest (MD) operations implemented by different supported crypto backends. The return values from these were not properly checked, which could cause low-memory situations failures, NULL dereferences, crashes, or usage of the uninitialized memory as an input for the KDF. In this case, non-matching keys will result in decryption/integrity failures, terminating the connection.
