Technical Description

Multiple vulnerabilities have been identified in MySQL, which could be exploited by malicious users to cause a denial of service or bypass security restricitons.

The first issue is caused by an error when using "RENAME TABLE". For additional information, see : VUPEN/ADV-2007-4142

The second weakness is caused by an error in the "ALTER VIEW" query that retains the original DEFINER value, which could allow a malicious user to gain the access rights of the view.

The third vulnerability is caused by an error when using a FEDERATED table, which could be exploited to cause the local server to crash when the remote server returns a result with fewer columns than expected.
