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

========
TimeLine
========
Discovered: 27 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 stack buffer overflow in the verifydb utility, which is runs
as setuid( ingres ) and is accessible to all users by default on unix
systems.

=================
Technical Details
=================
The Ingres verifydb utility parses command line arguments in the
duve_get_args function in the file duveutil.c. When an argument of the
form
-dbms_testAAAAAAAAAAAAAA...<lots of As> is passed, the following code is
executed:

	    case 'd':	    /* debug flag - should be 1st parameter */
		if (MEcmp((PTR)argv[parmno], (PTR)"-dbms_test", (u_i2)10)
                    ==DU_IDENTICAL )
		{
		    char    numbuf[100];    /* scratch pad to read in number*/
		    /* the DBMS_TEST flag was specified.  See if a numeric
		    ** value was attached to it.  If so, convert to decimal.
		    */
		    if (argv[parmno][10])
		    {
			STcopy (&argv[parmno][10], numbuf);
			cv_numbuf(numbuf, &duve_cb->duve_dbms_test);
		    }
		    else
			duve_cb->duve_dbms_test = -1;
		}
		else
		    duve_cb->duve_debug = TRUE;
		break;

The argument data beyond the string '-dbms_test' is copied into the
buffer 'numbuf' using the STcopy function, with no length check of the
copied data. This results in variables on the stack being overwritten,
including the saved return address.
