The Cascading Style Sheets (CSS) implementation in Microsoft Internet Explorer 8.0 and earlier does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.
The JavaScript implementation in Microsoft Internet Explorer 8.0 and earlier does not properly restrict the set of values contained in the object returned by the getComputedStyle method, which allows remote attackers to obtain sensitive information about visited web pages by calling this method.
Microsoft Internet Explorer 6 and 7 does not initialize certain data structures during execution of the createElement method, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted JavaScript code, as demonstrated by setting the (1) outerHTML or (2) value property of an object returned by createElement.
Microsoft Internet Explorer before 8 displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.
Microsoft Internet Explorer before 8 uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack.
Microsoft Internet Explorer 6 and 7 allows remote attackers to execute arbitrary code via uninitialized or deleted objects used in repeated calls to the (1) cloneNode or (2) nodeValue JavaScript function, a different issue than CVE-2007-3902 and CVE-2007-5344, a variant of "Uninitialized Memory Corruption Vulnerability."
Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code via a crafted website using Javascript that creates, modifies, deletes, and accesses document objects using the tags property, which triggers heap corruption, related to uninitialized or deleted objects, a different issue than CVE-2007-3902 and CVE-2007-3903, and a variant of "Uninitialized Memory Corruption Vulnerability."
Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code via "unexpected method calls to HTML objects," aka "DHTML Object Memory Corruption Vulnerability."
Microsoft Internet Explorer 4.0 through 7 allows remote attackers to determine the existence of local files that have associated images via a res:// URI in the src property of a JavaScript Image object, as demonstrated by the URI for a bitmap image resource within a (1) .exe or (2) .dll file.
danim.dll in Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (application crash) by accessing the Data property of a DirectAnimation DAUserData object before it is initialized, which triggers a NULL pointer dereference.
Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by setting the Filter property of an ADODB.Recordset ActiveX object to certain values multiple times, which triggers a null dereference.
pnxr3260.dll in the RealOne 2.0 build 6.0.11.868 browser plugin, as used in Internet Explorer, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted embed tag.
Internet Explorer 6.0 does not warn users when an expired certificate authority (CA) certificate is submitted to the user and a newer CA certificate is in the user's local repository, which could allow remote attackers to decrypt web sessions via a man-in-the-middle (MITM) attack.
