--------------------------------------------------------
Key: CORE-6185
URL: http://tracker.firebirdsql.org/browse/CORE-6185
Project: Firebird Core
Issue Type: Bug
Affects Versions: 4.0 Beta 1
Reporter: Pavel Zotov
Following examples lead FB to crash:
1) select encrypt( 'fooriobar' using CHACHA20 key q'{1110FB89-AD32-4E}' iv
q'{114E811E}' counter cast(null as bigint) ) from rdb$database;
2) script:
=======
set list on;
set blob all;
set bail on;
shell del C:\temp\c5970.fdb 2>nul;
create database 'localhost:C:\temp\c5970.fdb';
show version;
create or alter procedure sp_block_test(a_alg varchar(30)) as begin end;
commit;
recreate table test( crypto_alg varchar(30), source_text blob, crypto_key
varchar(128), crypto_iv varchar(16) );
commit;
insert into test( crypto_alg, source_text, crypto_key, crypto_iv) values(
'AES', lpad('', 65535, gen_uuid()), '0101010101010101', lpad('',16,
uuid_to_char( gen_uuid() )) );
commit;
set term ^;
create or alter procedure sp_block_test(a_alg varchar(30)) as
declare v_encrypted blob;
declare v_encrypt_sttm blob;
begin
for
select
t.source_text
,t.crypto_alg
,t.crypto_key
,t.crypto_iv
from test t
where upper( t.crypto_alg ) = upper( :a_alg )
as cursor c
do begin
v_encrypt_sttm = 'select encrypt( q''{' || c.source_text || '}''
using ' || c.crypto_alg || ' mode ofb key q''{' || c.crypto_key || '}'' iv
q''{' || c.crypto_iv || '}'' ) from rdb$database';
execute statement v_encrypt_sttm into v_encrypted;
end
end
^
set term ;^
commit;
set echo on;
execute procedure sp_block_test('aes');
