pointer and divide by zero. An authenticated user could exploit this
with a crafted IF clause, leading to a denial of service. (CVE-2007-2583)

Victoria Reznichenko discovered that MySQL did not always require the
DROP privilege. An authenticated user could exploit this via RENAME
TABLE statements to rename arbitrary tables, possibly gaining additional
database access. (CVE-2007-2691)

It was discovered that MySQL could be made to overflow a signed char
during authentication. Remote attackers could use crafted authentication
requests to cause a denial of service. (CVE-2007-3780)

Phil Anderton discovered that MySQL did not properly verify access
privileges when accessing external tables. As a result, authenticated
users could exploit this to obtain UPDATE privileges to external
tables. (CVE-2007-3782)

In certain situations, when installing or upgrading mysql, there was no
notification that the mysql root user password needed to be set. If the
password was left unset, attackers would be able to obtain unrestricted
access to mysql. This is now checked during mysql start-up.");
