What is the VENOM vulnerability?

VENOM is an unchecked buffered vulnerability which affects the open source QEMU virtualization platform which provides virtualization capabilities similar to VMWare or Microsoft’s Hyper-V. The unchecked buffer vulnerability (CVE-2015-3456) occurs in the code for QEMU’s virtual floppy disk controller. A successful buffer overflow attack exploiting this vulnerability can enable an attacker to execute his or her code in the hypervisor’s security context and escape from the guest operating system to gain control over the entire host.

Who is impacted by VENOM?

Products and technologies that utilize QEMU may be affected. However, because QEMU is an open source package it’s nearly impossible to know all affected products or services. It has been reported that Xen, KVM, and the native QEMU clients may be affected.

It has been confirmed that VMWare, Microsoft, and Bochs hypervisors are not impacted. Amazon has also stated that their AWS platform is not affected.

Fore more details on the VENOM vulnerability, refer to the following Trend Micro blog entry: Understanding the VENOM Vulnerability


At this time, QEMU and ZEN already have patches available, which should be applied as soon as possible. Other vendors are working on patches as well.

What Trend Micro products are affected?

Our major cloud-based and virtualization protection technologies such as Trend Micro Deep Security, Trend Micro Deep Discovery, and Trend Micro Hosted Email Security (HES) are confirmed not to utilize QEMU in their default configurations, so they are unaffected by this new vulnerability.

Please note, however, that components such as the Deep Discovery customer sandbox are highly configurable and components can be added for specific customer configurations. Customers who may have added additional components, such as floppy drive emulation, are encouraged to disable or verify these components if they are not deemed critical for proactive protection.

In addition, Trend Micro’s Product Vulnerability Response and Service Engineering teams are conducting a thorough analysis of the rest of our products and services to identify if any technologies may be affected.

As of this writing, no Trend Micro products have been found to be affected, but if any products are identified, the relevant information, including any necessary patches or fixes will be updated in this article.

What if my product is not listed?

If the product has not reached End-of-Support, it is most likely that Trend Micro is still analyzing the vulnerability and its impact on your product. As soon as the analysis is completed, the product will be added in the list.
