Description:
Several vulnerabilities were reported in Microsoft XML Core Services (MSXML). A remote user can cause arbitrary code to be executed on the target user's system. A remote user can obtain information from the target user's system.
A remote user can create HTML with specially crafted XML that, when loaded by the target user via Internet Explorer, will trigger a flaw in the XML parser and execute arbitrary code on the target system [CVE-2007-0099]. The code will run with the privileges of the target user.
A remote user can create HTML that, when loaded by the target user via Internet Explorer, will trigger a flaw in the error checking of external document type definitions (DTDs) and access information from arbitrary domains on the target user's browser [CVE-2008-4029].
A remote user can create specially crafted HTML that, when loaded by the target user via Internet Explorer, will trigger a flaw in the processing of transfer-encoding headers and access information from arbitrary domains on the target user's browser [CVE-2008-4033].
Gregory Fleischer, Stefano Di Paola of Minded Security, Robert Hansen of SecTheory, and Michal Zalewski reported these vulnerabilities.
