Remote exploitation of a memory corruption vulnerability in Microsoft Corp.'s Internet Explorer could allow an attacker to execute arbitrary code with the privileges of the current user.
During the instantiation of multiple ActiveX Controls, a particular object is created along with multiple references that point to the object. The object can be destroyed and its associated references removed. However, a reference can incorrectly remain pointing to the object. The invalid object resides in uninitialized memory, which the attacker may control to gain arbitrary execution control.
Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the user viewing the web page. To exploit this vulnerability, a targeted user must load a malicious webpage created by an attacker. An attacker typically accomplishes this via social engineering or injecting content into a compromised, trusted site.
Microsoft Internet Explorer 6, 7 and 8 are vulnerable.
Microsoft suggested workarounds can be found in Microsoft Security Bulletin MS10-090.
