Disclosure Date


Oracle VM VirtualBox contains an overflow condition in the Core subcomponent. The issue is triggered as user-supplied input is not properly validated by the cbCmdSize variable when handling HGCM (Host-Guest Communication Manager) call VMMDev requests. With a specially crafted request, a local attacker can cause a buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
