"Jason Geffner, CrowdStrike Senior Security Researcher reports :

VENOM, CVE-2015-3456, 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.");
