"The version of MySQL Community Server installed on the remote host is
earlier than 5.1.47 / 5.0.91 and is, therefore, potentially affected
by the following vulnerabilities :

  - The server may continue reading packets indefinitely
    if it receives a packet larger than the maximum size
    of one packet, which could allow an unauthenticated,
    remote attacker to consume a high level of CPU
    and bandwidth. (Bug #50974)

  - Using an overly long table name argument to the
    'COM_FIELD_LIST' command, an authenticated user can
    overflow a buffer and execute arbitrary code on the
    affected host. (Bug #53237)

  - Using a specially crafted table name argument to
    'COM_FIELD_LIST', an authenticated user can bypass
    almost all forms of checks for privileges and table-
    level grants. (Bug #53371)");
