Unspecified vulnerability in the setRequestHeader method in the XMLHTTP (XML HTTP) ActiveX Control 4.0 in Microsoft XML Core Services 4.0 on Windows, when accessed by Internet Explorer, allows remote attackers to execute arbitrary code via crafted arguments that lead to memory corruption, a different vulnerability than CVE-2006-4685. NOTE: some of these details are obtained from third party information.

The XMLHTTP ActiveX control in Microsoft XML Parser 2.6 and XML Core Services 3.0 through 6.0 does not properly handle HTTP server-side redirects, which allows remote user-assisted attackers to access content from other domains.
