New! Plugin Severity Now Using CVSS v3

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

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.

Solution

Update the affected packages.
