The AccessArray function in the VBScript engine of Internet Explorer is prone to a redefinition attack.
By accessing a VBScript array using a specially crafted object as the index, it is possible to resize the array in the middle of the AccessArray function, leaving the array in an inconsistent state, which can be abused by an attacker to execute arbitrary code on systems running vulnerable versions of Internet Explorer.
