Impact	DoS (Denial of Service) This includes vulnerabilities ranging from excessive resource consumption (e.g. causing a system to use a lot of memory) to crashing an application or an entire system. System access This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user. Cross-Site Scripting Cross-Site Scripting vulnerabilities allow a third party to manipulate the content or behaviour of a web application in a user's browser, without compromising the underlying system. Different Cross-Site Scripting related vulnerabilities are also classified under this category, including "script insertion" and "cross-site request forgery". Cross-Site Scripting vulnerabilities are often used against specific users of a website to steal their credentials or to conduct spoofing attacks.
Description	Multiple vulnerabilities have been reported in Microsoft XML Core Services, which can be exploited by malicious people to gain knowledge of sensitive information or potentially compromise a user's system. 1) A race condition when parsing XML content can be exploited to corrupt memory by reloading specially crafted XML files with nested tags in multiple iframes. Successful exploitation may allow execution of arbitrary code by e.g. tricking a user into visiting a malicious website. NOTE: This vulnerability only affects systems with Microsoft XML Core Services 3.0 installed. 2) An error in the handling of error checks for external document type definitions (DTDs) can be exploited to violate the cross-domain policy and read contents from another domain when a user e.g. visits a malicious website or views a specially crafted HTML e-mail. NOTE: This vulnerability only affects systems with Microsoft XML Core Services 3.0 or Microsoft XML Core Services 4.0 installed. 3) An error in the handling of transfer-encoding headers can be exploited to violate the cross-domain policy and read contents from another domain when a user e.g. visits a malicious website or views a specially crafted HTML e-mail.
