Security Alert CVE-2015-3456 Released

Fri, 2015-05-15 13:52

Hi, this is Eric Maurice.

Oracle just released Security Alert CVE-2015-3456 to address the recently publicly disclosed VENOM vulnerability, which affects various virtualization platforms. This vulnerability results from a buffer overflow in the QEMU's virtual Floppy Disk Controller (FDC).

While the vulnerability is not remotely exploitable without authentication, its successful exploitation could provide the malicious attacker, who has privileges to access the FDC on a guest operating system, with the ability to completely take over the targeted host system. As a result, a successful exploitation of the vulnerability can allow a malicious attacker with the ability to escape the confine of the virtual environment for which he/she had privileges for. This vulnerability has received a CVSS Base Score of 6.2.

Oracle has decided to issue this Security Alert based on a number of factors, including the potential impact of a successful exploitation of this vulnerability, the amount of detailed information publicly available about this flaw, and initial reports of exploit code already “in the wild.” Oracle further recommends that customers apply the relevant fixes as soon as they become available.

Oracle has also published a list of Oracle products that may be affected by this vulnerability. This list will be updated as fixes become available.

The Oracle Security and Development teams are also working with the Oracle Cloud teams to ensure that the Oracle Cloud teams can evaluate these fixes as they become available and be able to apply the relevant patches in accordance with applicable change management processes in these organizations.

April 2015 Critical Patch Update Released

Tue, 2015-04-14 14:17

Hello, this is Eric Maurice.

Oracle today released the April 2015 Critical Patch Update. The predictable nature of the Critical Patch Update program is intended to provide customers the ability to plan for the application of security fixes across all Oracle products. Critical Patch Updates are released quarterly in the months of January, April, July, and October. Unfortunately, Oracle continues to periodically receive reports of active exploitation of vulnerabilities that have already been fixed by Oracle in previous Critical Patch Update releases. In some instances, malicious attacks have been successful because customers failed to apply Critical Patch Updates. The “Critical” in the designation of the Critical Patch Update program is intended to highlight the importance of the fixes distributed through the program. Oracle highly recommends that customers apply these Critical Patch Updates as soon as possible. Note that Critical Patch Updates are cumulative for most Oracle products. As a result, the application of the most recent Critical Patch Update brings customers to the most recent security release, and addresses all previously-addressed security flaws for these products. The Critical Patch Update release schedule for the next 12 calendar months is published on Oracle’s Critical Patch Updates, Security Alerts and Third Party Bulletin page on

The April 2015 Critical Patch Update provides 98 new fixes for security issues across a wide range of product families including: Oracle Database, Oracle Fusion Middleware, Oracle Hyperion, Oracle Enterprise Manager, Oracle E-Business Suite, Oracle Supply Chain Suite, Oracle PeopleSoft Enterprise, Oracle JDEdwards EnterpriseOne, Oracle Siebel CRM, Oracle Industry Applications, Oracle Java SE, Oracle Sun Systems Products Suite, Oracle MySQL, and Oracle Support Tools.

Out of these 98 new fixes, 4 are for the Oracle Database. None of the database vulnerabilities are remotely exploitable without authentication. The most severe of the database vulnerabilities (CVE-2015-0457) has received a CVSS Base Score 9.0 only for Windows for Database versions prior to 12c. This Base Score is 6.5 for Database 12c on Windows and for all versions of Database on Linux, Unix and other platforms. This vulnerability is related to the presence of the Java Virtual Machine in the database.

17 of the vulnerabilities fixed in this Critical Patch Update are for Oracle Fusion Middleware. 12 of these Fusion Middleware vulnerabilities are remotely exploitable without authentication, and the highest reported CVSSS Base Score is 10.0. This CVSS10.0 Base Score is for CVE-2015-0235 (a.k.a. GHOST which affects the GNU libc library) affecting the Oracle Exalogic Infrastructure.

This Critical Patch Update also delivers 14 new security fixes for Oracle Java SE. 11 of these Java SE fixes are for client-only (i.e., these vulnerabilities can be exploited only through sandboxed Java Web Start applications and sandboxed Java applets). Two apply to JSSE client and Server deployments and 1 to Java client and Server deployments. The Highest CVSS Base Score reported for these vulnerabilities is 10.0 and this score applies to 3 of the Java vulnerabilities (CVE-2015-0469, CVE-2015-0459, and CVE-2015-0491).

For Oracle Applications, this Critical Patch Update provides 4 new fixes for Oracle E-Business Suite , 7 for Oracle Supply Chain Suite, 6 for Oracle PeopleSoft Enterprise, 1 for Oracle JDEdwards EnterpriseOne, 1 for Oracle Siebel CRM, 2 for the Oracle Commerce Platform, and 2 for Oracle Retail Industry Suite, and 1 for Oracle Health Sciences Applications.

Finally, this Critical Patch Update provides 26 new fixes for Oracle MySQL. 4 of the MySQL vulnerabilities are remotely exploitable without authentication and the maximum CVSS Base Score for the MySQL vulnerabilities is 10.0.

As stated at the beginning of this blog, Oracle recommends that customers consistently apply Critical Patch Update as soon as possible. The security fixes provided through the Critical Patch Update program are thoroughly tested to ensure that they do not introduce regressions across the Oracle stack. Extensive documentation is available on the My Oracle Support Site and customers are encouraged to contact Oracle Support if they have questions about how to best deploy the fixes provided through the Critical Patch Update program.
