Essent and its Products and Services Unaffected by VENOM Vulnerability


You should bring this Support Notice to the attention of your Information Technology (IT) department or webmaster.


A critical security vulnerability known as Virtualized Environment Neglected Operations Manipulation (VENOM) allows attackers to access virtual machines.

Virtual machines are computers simulated within other computers and are presumed to be isolated and secure. The VENOM vulnerability allows an attacker to leave one virtual machine, gain access to other virtual machines operating on the same host, and ultimately gain access to the host.

Exploitation of VENOM can compromise credentials, intellectual property, Personally Identifiable Information and other confidential or sensitive information.

This vulnerability has been assigned CVE identifier CVE-2015-3456.

According to CrowdStrike: "VENOM … is a security vulnerability in the virtual floppy drive code used by many computer virtualization platforms. This vulnerability may allow an attacker to escape from the confines of an affected virtual machine (VM) guest and potentially obtain code-execution access to the host. Absent mitigation, this VM escape could open access to the host system and all other VMs running on that host, potentially giving adversaries significant elevated access to the host’s local network and adjacent systems.”
