Overview Microsoft Internet Explorer (IE) contains multiple vulnerabilities, the most serious of which could allow a remote attacker to execute arbitrary code with the privileges of the user running IE. Description Microsoft Security Bulletin MS04-004 describes three vulnerabilities in Internet Explorer. These vulnerabilities are listed below. More detailed information is available in the individual vulnerability notes. Note that in addition to IE, any applications that use the IE HTML rendering engine to interpret HTML documents may present additional attack vectors for these vulnerabilities. VU#784102 - Microsoft Internet Explorer Travel Log Cross Domain Vulnerability A cross-domain scripting vulnerability exists in the Travel Log functionality of Internet Explorer. This vulnerability could allow a remote attacker to execute arbitrary script in a different domain, including the Local Machine Zone. (Other resources: CAN-2003-01026) VU#413886 - Microsoft Internet Explorer Drag-and-Drop Operation Vulnerability Internet Explorer allows remote attackers to direct drag and drop behaviors and other mouse click actions by using method caching (SaveRef) to access the window.moveBy method. (Other resources: CAN-2003-01027) VU#652278 - Microsoft Internet Explorer does not properly display URLs Microsoft Internet Explorer does not properly display the location of HTML documents. An attacker could exploit this behavior to mislead users into revealing sensitive information. (Other resources: CAN-2003-01025) Impact These vulnerabilities have different impacts, ranging from disguising the true location of a URL to executing arbitrary commands or code. Please see the individual vulnerability notes for specific information. The most serious of these vulnerabilities (VU#784102) could allow a remote attacker to execute arbitrary code with the privileges of the user running IE. The attacker could exploit this vulnerability by convincing the user to access a specially crafted HTML document, such as a web page or HTML email message. No user intervention is required beyond viewing the attacker's HTML document with IE. Solutions Apply a patch Apply the appropriate patch as specified by Microsoft Security Bulletin MS04-004. * Microsoft Security Bulletin MS04-004 - <http://microsoft.com/technet/security/bulletin/MS04-004.asp> Note: The fix included in MS04-004 for VU#652278 may cause sites that use URLs of the form "username:email@example.com" to break.
