Microsoft XML Core Services 3.0, 4.0, 5.0, and 6.0 accesses uninitialized memory locations, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site.

Microsoft XML Core Services (aka MSXML) 3.0, 5.0, and 6.0 does not properly parse XML content, which allows remote attackers to execute arbitrary code via a crafted web page, aka "MSXML Integer Truncation Vulnerability."

Microsoft XML Core Services (aka MSXML) 4.0, 5.0, and 6.0 does not properly parse XML content, which allows remote attackers to execute arbitrary code via a crafted web page, aka "MSXML XSLT Vulnerability."

Cross-domain vulnerability in Microsoft XML Core Services 3.0 through 6.0, as used in Microsoft Expression Web, Office, Internet Explorer, and other products, allows remote attackers to obtain sensitive information from another domain and corrupt the session state via HTTP request header fields, as demonstrated by the Transfer-Encoding field, aka "MSXML Header Request Vulnerability."

Microsoft XML Core Services (MSXML) 3.0 through 6.0 allows remote attackers to execute arbitrary code via the substringData method on a (1) TextNode or (2) XMLDOM object, which causes an integer overflow that leads to a buffer overflow.

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.

Buffer overflow in the Extensible Stylesheet Language Transformations (XSLT) processing in Microsoft XML Parser 2.6 and XML Core Services 3.0 through 6.0 allows remote attackers to execute arbitrary code via a crafted Web page.

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.

XMLHTTP control in Microsoft XML Core Services 2.6 and later does not properly handle IE Security Zone settings, which allows remote attackers to read arbitrary files by specifying a local file as an XML Data Source.
