Multiple Critical and High Vulnerabilities in Oracle Database Server



David Litchfield of NGSSoftware has discovered discovered multiple critical and high risk vulnerabilities in the Oracle Database Server. These vulnerabilities can be exploited by an attacker to gain complete control of the database server. Versions affected include

Oracle Database 10g - All Releases
Oracle9i Database Server - All Releases

The vulnerabilities include a buffer overflow vulnerability and seventeen PL/SQL injection vulnerabilities and Oracle has released a patch set to deal with these issues. It is understood that this patch set fixes a number of other flaws found by seven other security researchers. Oracle database administrators are urged to download, test and install the patch set as soon as possible. See http://www.oracle.com/technology/deploy/security/pdf/cpuoct2005.html for more details.

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. More information about NGSSQuirreL for Oracle can be found at http://www.ngssoftware.com/squirrelora.htm.

NGSSoftware are going to withhold details about these flaws for three months. Full details will be published on the 18th of January 2006. 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.
