Technical Analysis
This vulnerability is a Use-After-Free in the Microsoft VBScript engine. Originally exploited in the wild, attackers used a technique to force the exploit code to be opened with Internet Explorer by embedding a resource into a Rich Text File (RTF). This technique would allow attackers to more reliably exploit targets, even when a non-IE browser was configured as the default.
The Use After Free is related to arbitrary VB object. When two arrays reference the same object, and one array is deleted, the second array is left with a dangling reference.
