//@(#)Mordred Labs advisory 0x0003
Release data: 20/08/02
Name: Buffer overflow in PostgreSQL
Versions affected: all versions
Risk: high
--[ Description:
...PostgreSQL is a sophisticated Object-Relational DBMS,
supporting almost all SQL constructs, including subselects,
transactions, and user-defined types and functions. It is the
most advanced open-source database available anywhere...blah...blah...

http://www.postgresql.org/idocs/index.php?preface.html#INTRO-WHATIS
There exists a heap buffer overflow in a repeat(text, integer) function,
which
allows an attacker to execute malicious code.
--[ Details:
Upon invoking a repeat() function, a
src/backend/utils/adt/oracle_compat.c::repeat() function
will gets called which suffers from a buffer overflow.
--[ How to reproduce:
psql> select repeat('xxx',1431655765);
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
--[ Solution
Do you still running postgresql? ...Can't believe that...
If so, execute the following command as a root: "killall -9 postmaster",
and wait until the patch will be available.
