Systems Affected: Ingres 2006 9.0.4 and prior
Risk: Critical
Status: Published

=======TimeLine
=======Discovered: 29 March 2006

==========Description
==========Ingres 2006 is a venerable and functionality-rich RDBMS that has
recently been made available under the Gnu Public License (GPL).

There is a controllable pointer overwrite vulnerability in Ingres 2006
that occurs prior to authentication, that could allow an unauthenticated
attacker to execute arbitrary code within the context of the database
server.

================Technical Details
================The Ingres Communications Server Process (iigcc) listens on TCP port
21064 in a default Linux install of Ingres 2006.

If a connection is made and data of a specific form is sent to this TCP
port twice in rapid succession, iigcc will call the QUremove function
with an attacker-controlled argument. QUremove then overwrites an
address controlled by the attacker with a value controlled by the
attacker, thereby allowing the attacker to gain control of the flow of
execution.

The stack trace at the point of the controllable overwrite is as follows:

(gdb) info stack
#0  0x08089648 in QUremove ()
#1  0x0805f08a in gcc_al ()
#2  0x0805aabf in gcc_plout_exec ()
#3  0x080598ee in gcc_pl_event ()
#4  0x080596e4 in gcc_pl ()
#5  0x080595b5 in gcc_slout_exec ()
#6  0x0805794c in gcc_sl_event ()
#7  0x08057744 in gcc_sl ()
#8  0x0805692e in gcc_tlout_exec ()
#9  0x08054469 in gcc_tl_event ()
#10 0x08054238 in gcc_tl ()
#11 0x0805566a in gcc_tl_exit ()
#12 0x0809a25f in GCbssm ()
#13 0x08083b0e in ii_CL_poll_call ()
#14 0x08083921 in iiCLpoll ()
#15 0x08080122 in GCexec ()
#16 0x0805307c in main ()

Proof of concept code that demonstrates this issue has been provided to
the vendor.
