This vulnerability allows remote attackers to execute arbitrary code on affected installations of Oracle VirtualBox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within handling of D3D9 shader objects. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
