Remove security vulnerability that allowed connected users
to read backend memory (Tom)
</para>
<para>
The vulnerability involves suppressing the normal check that a SQL
function returns the data type it's declared to, or changing the
data type of a table column used in a SQL function (CVE-2007-0555).
This error 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.
