CVE-2020-14886: Oracle VirtualBox Shader Bytecode Out-Of-Bounds Read Information Disclosure Vulnerability
First published: Wed Oct 21 2020(Updated: )
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 shader_skip_unrecognized function. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the hypervisor.
