This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Microsoft Windows. 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 the handling of Microsoft ADO (ActiveX Data Objects) methods that accept an array as a parameter. By performing actions in script, an attacker can cause a pointer to be reused after it has been freed. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
