Oracle CPU - January 2015 Focus on Business Applications

As a company, Onapsis is focused on the security of business-critical applications such as SAP and Oracle. While our focus has been on SAP applications, we have also been actively researching, identifying and reporting critical vulnerabilities facing Oracle business applications. In this sense, Oracle is different from SAP, specifically in the way and timing that security patches are released and available to end users. In this post, I will go through an analysis of Oracle's January 2015 Critical Patch Update (aka CPU).

SAP and GHOST vulnerability (CVE-2015-0235)

Last week a new vulnerability was reported, affecting the GNU C library (glibc). This vulnerability affects a wide range of Linux distributions, among which are some supported by SAP products as stated in SAP Note 171356.

It's important to understand that even though this vulnerability does not directly affect any SAP application, it affects a lower layer, the operating system, allowing any application to potentially use the vulnerable function.

SAP Security Note 2067859 Potential Exposure to Digital Signature Spoofing

This week, SAP AG published a hot news item titled: "SAP Security Note 2067859 (Potential Exposure to Digital Signature Spoofing)", which alerts users about a potential vulnerability in certain cryptographic libraries used in SAP NetWeaver Application Server ABAP and SAP HANA. By abusing these libraries, an attacker could potentially spoof (i.e., successfully masquerade as a legitimate user) Digital Signatures produced in vulnerable systems.
