Remove security vulnerabilities that allowed connected users
to read backend memory (Tom)
</para>
<para>
The vulnerabilities involve suppressing the normal check that a SQL
function returns the data type it's declared to, and changing the
data type of a table column (CVE-2007-0555, CVE-2007-0556). These
errors can easily be exploited to cause a backend crash, and in
principle might be used to read database content that the user
should not be able to access.
