Researchers at NGSSoftware have discovered multiple high risk vulnerabilities in the Oracle Database Server. Versions affected include Oracle Database 10g - All Releases Oracle9i Database Server - All Releases The vulnerabilities include PL/SQL Injection vulnerabilities that allow low privileged users to gain DBA privileges and a buffer overflow vulnerability. The former can be exploited via the web through Oracle Application Server. Oracle has released a patch set (18/01/2005) to address these issues. Oracle database administrators are urged to download, test and install the patch set as soon as possible. See http://metalink.oracle.com/ for more details. NGSSoftware are going to withhold details about these flaws for three months. Full details will be published on the 18th of April 2005. This three month window will allow Oracle database administrators the time needed to test and apply the patch set before the details are released to the general public. This reflects NGSSoftware's new approach to responsible disclosure. NGSSQuirreL for Oracle, NGSSoftware's advanced vulnerability assessment scanner and security manager for Oracle, has been updated to check for and positively identify these flaws in Oracle database servers on the network.
