Microsoft Internet Explorer 6 and 7 does not properly determine the domain or security zone of origin of web script, which allows remote attackers to bypass the intended cross-domain security policy, and execute arbitrary code or obtain sensitive information, via a crafted HTML document, aka "Event Handling Cross-Domain Vulnerability."

Microsoft Internet Explorer 6 does not properly handle errors related to using the componentFromPoint method on xml objects that have been (1) incorrectly initialized or (2) deleted, which allows remote attackers to execute arbitrary code via a crafted HTML document, aka "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 6 and 7 does not properly determine the domain or security zone of origin of web script, which allows remote attackers to bypass the intended cross-domain security policy, and execute arbitrary code or obtain sensitive information, via a crafted HTML document, aka "HTML Element Cross-Domain Vulnerability."

Microsoft Internet Explorer 6 and 7 does not properly determine the domain or security zone of origin of web script, which allows remote attackers to bypass the intended cross-domain security policy and obtain sensitive information via a crafted HTML document, aka "Cross-Domain Information Disclosure Vulnerability."

Microsoft Internet Explorer 5.01 SP4 and 6 does not properly handle errors associated with access to uninitialized memory, which allows remote attackers to execute arbitrary code via a crafted HTML document, aka "HTML Objects Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01, 6, and 7 accesses uninitialized memory in certain conditions, which allows remote attackers to cause a denial of service (crash) and execute arbitrary code via vectors related to a document object "appended in a specific order," aka "HTML Objects Memory Corruption Vulnerability" or "XHTML Rendering Memory Corruption Vulnerability," a different vulnerability than CVE-2008-2258.

Microsoft Internet Explorer 5.01, 6, and 7 does not properly handle objects that have been incorrectly initialized or deleted, which allows remote attackers to cause a denial of service (crash) and execute arbitrary code via unknown vectors, aka "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01, 6, and 7 accesses uninitialized memory, which allows remote attackers to cause a denial of service (crash) and execute arbitrary code via unknown vectors, a different vulnerability than CVE-2008-2254, aka "HTML Object Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01, 6, and 7 accesses uninitialized memory in certain conditions, which allows remote attackers to cause a denial of service (crash) and execute arbitrary code via vectors related to a document object "appended in a specific order" with "particular functions ... performed on" document objects, aka "HTML Objects Memory Corruption Vulnerability" or "Table Layout Memory Corruption Vulnerability," a different vulnerability than CVE-2008-2257.

Cross-domain vulnerability in Microsoft Internet Explorer 5.01 SP4, 6, and 7 allows remote attackers to access restricted information from other domains via JavaScript that uses the Object data type for the value of a (1) location or (2) location.href property, related to incorrect determination of the origin of web script, aka "Window Location Property Cross-Domain Vulnerability." NOTE: according to Microsoft, CVE-2008-2948 and CVE-2008-2949 are duplicates of this issue, probably different attack vectors.
