CVE-2020-14884: Oracle VirtualBox Shader Bytecode Type Confusion Information Disclosure Vulnerability
This vulnerability allows local attackers to disclose sensitive information on affected installations of Oracle VirtualBox. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the shaderrecordregisterusage function. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the hypervisor.
