Executive Summary

This vulnerability exists in the sqlo_place_dt_set component of openlink virtuoso-opensource version 7.2.11. It allows attackers to cause a Denial of Service (DoS) by submitting specially crafted SQL statements that trigger a crash in the system.

The issue was discovered through fuzz testing, where a specific SQL query involving creating a table with a REAL column and performing an UPDATE with a nested SELECT causes the crash. The crash occurs in the sqlo_place_dt_set function, leading to the application becoming unresponsive.

Detection Guidance

This vulnerability can be detected by attempting to reproduce the crash using the specific SQL query that triggers the issue in the sqlo_place_dt_set function of Virtuoso 7.2.11.

The detection involves running a crafted SQL query that creates a table with a REAL column and performs an UPDATE operation with a nested SELECT statement, which was identified by a DBMS fuzzer.

The reporter provided steps to reproduce the issue using a Docker container, including commands to remove an old container, start a new one, and execute the problematic SQL query.

• Remove old Docker container: docker rm -f virtuoso-test
• Start a new Docker container with the beta image: docker run -d --name virtuoso-test openlink/virtuoso-opensource:beta
• Execute the problematic SQL query inside the container to trigger the crash.
