Problem

Address Space Layout Randomization (ASLR) is a vulnerability mitigation option that forces software components to load on a different memory base address each time they are used. This mitigation is detected as enabled, but rendered ineffective due to the lack of code relocations necessary for layout randomization. This issue is reported for native 32-bit applications that contain code and opt in to use ASLR. Reasons for relocation absence include forcing software component load on a fixed address, removing relocations post-build, and using non-ASLR-compliant executable packing solutions.

Problem

Software developers use programming and design knowledge to build reusable software components. Software components are the basic building blocks for modern applications. Software consumed by an enterprise consists of hundreds, and sometimes even thousands of open source components. Open source communities depend on the work of thousands of software developers that volunteer their time to maintain software components. Software developers build up the reputation of their open source projects by developing in public. Modern source code repositories have many social features that allow software developers to handle bug reports, have discussions with their users, and convey reaching significant project milestones. It is uncommon to find open source projects that omit linking their component to a publicly accessible source code repository.

Next steps

Check the software component behaviors for anomalies.
Consider exploratory software component testing within a sandbox environment.
Consider replacing the software component with a more widely used alternative.
Avoid using this software package until it is vetted as safe.
