Authenticated partial denial of service
Published Jul 20, 2021 · Updated Sep 26, 2024
Denial of service in Oracle Database 19c Core RDBMS allows remote authenticated users to interrupt service through Oracle Net. Oracle identifies the Core RDBMS and Create Table privilege gate but has not published the malformed operation or input that triggers the fault. Exploitation requires Create Table privilege, and the reported consequence is limited to partial service interruption.
