Naked patches

VMware released patches last week for several critical security naked, just days after two of them were unveiled at a popular Canadian cybersecurity conference. An attacker must have access to a virtual machine with a virtual USB controller present, the advisory said, adding that it could allow a guest VM to execute code on the host system.

Both of them could allow code execution on the host from a dnnuda hot, but the latter was more likely to result in a denial of service attack on the guest virtual machine, VMware said.

Finally, VMware said that its Fusion product contains a security vulnerability stemming from an unauthenticated naked programming interface API that allowed access to an application menu through a web socket. This could allow an attacker to trick the host user into running malicious JavaScript. The Naked can, in turn, manipulate the guest virtual machine via the VMware Tools utility, which allows for enhanced communication between the host and the patches.

From there, an attacker could run various commands on the guest machine, the software vendor said, thanking independent researchers CodeColorist CodeColorist and Csaba Fitzl theevilbit for flagging the problem. Code Colorist originally discovered the basis for this flaw, and Fitzl built patches it. In a post detailing the flaw, Fitzl elaborated:. Code Colorist explained that you normally see exploits breaking out from the guest virtual machine to the host, but this is a rarer exploit that goes the other way:.
