mshtml.dll in Microsoft Internet Explorer 7 and 8 on Windows XP SP3 allows remote attackers to cause a denial of service (application crash) by calling the JavaScript findText method with a crafted Unicode string in the first argument, and only one additional argument, as demonstrated by a second argument of -1.
Microsoft Internet Explorer 6 SP1; Internet Explorer 6 for Windows XP SP2 and SP3 and Server 2003 SP2; and Internet Explorer 7 and 8 for Windows XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2 do not properly handle attempts to access deleted objects in memory, which allows remote attackers to execute arbitrary code via a crafted HTML document that triggers memory corruption, aka "Memory Corruption Vulnerability."
Microsoft Internet Explorer 5.01 SP4 and 6 SP1; Internet Explorer 6 for Windows XP SP2 and SP3 and Server 2003 SP2; and Internet Explorer 7 and 8 for Windows XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2 do not properly handle table operations, which allows remote attackers to execute arbitrary code via a crafted HTML document that triggers memory corruption by adding malformed elements to an empty DIV element, related to the getElementsByTagName method, aka "HTML Objects Memory Corruption Vulnerability."
Microsoft Internet Explorer 5.01 SP4 and 6 SP1; Internet Explorer 6 for Windows XP SP2 and SP3 and Server 2003 SP2; and Internet Explorer 7 and 8 for Windows XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2 do not properly handle attempts to access deleted objects in memory, which allows remote attackers to execute arbitrary code via an HTML document containing embedded style sheets that modify unspecified rule properties that cause the behavior element to be "improperly processed," aka "Uninitialized Memory Corruption Vulnerability."
Microsoft Internet Explorer 5 through 8 allows remote attackers to cause a denial of service (memory consumption and application crash) via a large integer value for the length property of a Select object, a related issue to CVE-2009-1692.
Stack-based buffer overflow in the AddFavorite method in Microsoft Internet Explorer allows remote attackers to cause a denial of service (application crash) and possibly have unspecified other impact via a long URL in the first argument.
Microsoft Internet Explorer 8, and possibly other versions, detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."
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 5.01 SP4; 6 SP1; 6 and 7 for Windows XP SP2 and SP3; 6 and 7 for Server 2003 SP2; 7 for Vista Gold, SP1, and SP2; and 7 for Server 2008 SP2 does not prevent HTML rendering of cached content, which allows remote attackers to bypass the Same Origin Policy via unspecified vectors, aka "Cross-Domain Information Disclosure Vulnerability."
