Oracle Database Server Java VM may let attackers alter data

CVE-2019-2749 · published 7 years ago
Summary

The Java engine inside Oracle Database Server versions 11.2.0.4, 12.1.0.2, 12.2.0.1, 18c and 19c can be tricked by a low‑privilege user who can create sessions and procedures. If exploited, the attacker could change, delete or add important data and could also cause the Java engine to freeze or crash, disrupting service. Apply the latest security updates from Oracle and restrict the create‑session and create‑procedure rights to only trusted accounts.
