Microsoft Internet Explorer 6.0.2900.2180 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption) via a long Unicode string argument to the write method, a related issue to CVE-2009-2479. NOTE: it was later reported that 7.0.6000.16473 and earlier are also affected.
Use-after-free vulnerability in Microsoft Internet Explorer 5.01 SP4, 6 through SP1, and 7 allows remote attackers to execute arbitrary code via a crafted data stream that triggers memory corruption, as demonstrated using an invalid MIME-type that does not have a registered handler.
Unspecified vulnerability in Microsoft Internet Explorer 5.01, 6 SP1 and SP2, and 7 allows remote attackers to execute arbitrary code via crafted HTML layout combinations, aka "HTML Rendering Memory Corruption Vulnerability."
Unspecified vulnerability in an ActiveX control (dxtmsft.dll) in Microsoft Internet Explorer 5.01, 6 SP1 and SP2, and 7 allows remote attackers to execute arbitrary code via a crafted image, aka "Argument Handling Memory Corruption Vulnerability."
Microsoft Internet Explorer allows remote attackers to cause a denial of service (crash) via an IFRAME with a certain XML file and XSL stylesheet that triggers a crash in mshtml.dll when a refresh is called, probably a null pointer dereference.
Microsoft Internet Explorer 6.0 SP1 on Windows 2000, and 6.0 SP2 on Windows XP, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an HTML document containing a certain JavaScript for loop with an empty loop body, possibly involving getElementById.
Microsoft Internet Explorer 5.01 through 6 allows remote attackers to execute arbitrary code via crafted layout combinations involving DIV tags and HTML CSS float properties that trigger memory corruption, aka "HTML Rendering Memory Corruption Vulnerability."
Multiple unspecified vulnerabilities in DirectAnimation ActiveX controls for Microsoft Internet Explorer 5.01 through 6 have unknown impact and remote attack vectors, possibly related to (1) Danim.dll and (2) Lmrt.dll, a different set of vulnerabilities than CVE-2006-4446 and CVE-2006-4777.
Internet Explorer 6 on Windows XP SP2 allows remote attackers to execute arbitrary JavaScript in the context of the browser's session with an arbitrary intranet web server, by hosting script on an Internet web server that can be made inaccessible by the attacker and that has a domain name under the attacker's control, which can force the browser to drop DNS pinning and perform a new DNS query for the domain name after the script is already running.
Microsoft Internet Explorer 5.01 and 6 does not properly identify the originating domain zone when handling redirects, which allows remote attackers to read cross-domain web pages and possibly execute code via unspecified vectors involving a crafted web page, aka "Source Element Cross-Domain Vulnerability."
