The PoC is generated by my DBMS fuzzer.

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-7:7.2.11

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

cat /tmp/test.sql | docker exec -i virtdb_test isql 1111 dba
