The PoC is generated by my DBMS fuzzer.

CREATE TABLE hist ( cnt VARCHAR NOT NULL, y VARCHAR NOT NULL, z VARCHAR, PRIMARY KEY (cnt,y) ); CREATE TABLE t19d AS (SELECT * FROM hist UNION ALL SELECT 1234);

backtrace:

#0 0x7f523bf87dbe (__libc_longjmp+0xde) #1 0x5177d573a547bfaf – no symbol name found

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”
