VMware has announced two critical vulnerabilities affecting multiple VMware products. CVE-2018-6981 and CVE-2018-6982 reference a guest-to-host escape, and a potential information leak between the host machine and the guest machine. Threat actors could exploit these vulnerabilities to execute code from a guest host machine, gaining root access on the host machine. Exploitation of these vulnerabilities requires either local access or a previous separate exploit to gain remote access. At the time of publishing, no known attacks using these vulnerabilities have been identified in the wild.
