Description

MySQL contains a flaw that may allow a malicious user to authenticate with the database without a password. The issue is triggered when a 4.1 protocol request occurs with a zero length password. It is possible that the flaw may allow arbitrary SQL command execution resulting in a loss of confidentiality and integrity.
