Oracle VENOM Vulnerability Patch Released

Number: AV15-048
Date: 19 May 2015

Purpose

The purpose of this advisory is to bring attention to a patch released by Oracle to address a critical vulnerability affecting multiple virtual platforms.

Assessment

Oracle has released a patch to address the critical vulnerability known as VENOM affecting multiple products they offer.

The Quick Emulator (QEMU) virtual Floppy Disk controller (FDC) code is vulnerable to an attacker escaping from the virtual machine guest system and potentially obtaining code-execution access to the host. Since the FDC module is part of the hypervisor, the vulnerability is indifferent to the host operating system. An attacker would need administrative or root privileges in the guest operating system to exploit this vulnerability.

CVE Reference: CVE-2015-3456

Suggested action

CCIRC recommends that owner/operators who utilize virtual environments based on Oracle products which utilize QEMU, test and deploy the appropriate update to affected platforms.
