VMware started rolling out software updates that address the GNU Bash vulnerability called ShellShock.

The list of VMware products affected by the vulnerability includes ESX, vCenter Server Appliance, Horizon Workspace, IT Business Management Suite, vCenter Log Insight, vCenter Operations Manager, vCenter Site Recovery Manager, vCloud Application Director, vCloud Automation Center, vCloud Director Appliance, vFabric Postgres, VMware Data Recovery, VMware Mirage Gateway, vSphere Replication and vSphere Storage Appliance. ESXi and Windows-based products do not suffer from the issue, the company said in its advisory.

Bash libraries have been updated only for solutions such as ESX, vCenter Server Appliance, IT Business Management Suite, vCenter Log Insight, vCenter Site Recovery Manager, vCloud Director Appliance, vFabric Postgres, VMware Data Recovery, VMware Mirage Gateway, vSphere Replication and vSphere Storage Appliance.

Until patches are available for all the products, VMware advises its customers to mitigate potential attacks by allowing access to affected appliances, through firewall rules and other network controls, only from trusted IP addresses.

The initial ShellShock vulnerability (CVE-2014-6271) ended up patched quickly. However, in the following days, several other related issues came to light: CVE-2014-7169, CVE-2014-7186, CVE-2014-7187, CVE-2014-6277 and CVE-2014-6278. VMware points out that its software updates remediate all of these problems.

“VMware’s Security Engineers have been closely monitoring and evaluating the various fixes being proposed within the security community. As such, VMware has adopted the more comprehensive solution suggested by Dr. Christos Zoulas of the NetBSD project last week,” said Monty Ijzerman, Sr. Program Manager of Product Security at VMware. “This broad fix removes access to the underlying function importing behavior in bash that exposes the fragile parsing code to external exploitation. We expect this broader fix to be more durable than point fixes as it will remove the risk due to future parser bugs.”

Apple, Oracle and Cisco also started releasing security updates for their products and, earlier this week, researchers reported even certain OpenVPN configurations are susceptible to ShellShock attacks.
