Microsoft Internet Explorer permits cross-origin loading of CSS stylesheets even when the stylesheet download has an incorrect MIME type and the stylesheet document is malformed, which allows remote HTTP servers to obtain sensitive information via a crafted document.

Use-after-free vulnerability in Microsoft Internet Explorer 6, 6 SP1, 7, and 8 on Windows 2000 SP4; Windows XP SP2 and SP3; Windows Server 2003 SP2; Windows Vista Gold, SP1, and SP2; Windows Server 2008 Gold, SP2, and R2; and Windows 7 allows remote attackers to execute arbitrary code by accessing a pointer associated with a deleted object, related to incorrectly initialized memory and improper handling of objects in memory, as exploited in the wild in December 2009 and January 2010 during Operation Aurora, aka "HTML Object Memory Corruption Vulnerability."

Microsoft Internet Explorer 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-3671.

Microsoft Internet Explorer 7 and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-3674.

Microsoft Internet Explorer 6.0.2900.2180 and earlier allows remote attackers to cause a denial of service (CPU consumption and application hang) via JavaScript code with a long string value for the hash property (aka location.hash), a related issue to CVE-2008-5715.

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.

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.

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.

Unspecified vulnerability in Microsoft Internet Explorer 5.01 SP4, 6 SP1, 6 on Windows XP SP2 and SP3, and 6 on Windows Server 2003 SP1 and SP2 allows remote attackers to execute arbitrary code via a web page that triggers presence of an object in memory that was (1) not properly initialized or (2) deleted, aka "Uninitialized Memory Corruption Vulnerability."

Multiple stack-based buffer overflows in the Research in Motion RIM AxLoader ActiveX control in AxLoader.ocx and AxLoader.dll in BlackBerry Application Web Loader 1.0 allow remote attackers to execute arbitrary code via unspecified use of the (1) load or (2) loadJad method.

Cross-site scripting (XSS) vulnerability in the XSS filter (framework/Text_Filter/Filter/xss.php) in Horde Application Framework 3.2.2 and 3.3, when Internet Explorer is being used, allows remote attackers to inject arbitrary web script or HTML via unknown vectors related to style attributes.

An unspecified function in the JavaScript implementation in Microsoft Internet Explorer creates and exposes a "temporary footprint" when there is a current login to a web site, which makes it easier for remote attackers to trick a user into acting upon a spoofed pop-up message, aka an "in-session phishing attack." NOTE: as of 20090116, the only disclosure is a vague pre-advisory with no actionable information. However, because it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Cross-domain vulnerability in Microsoft XML Core Services 3.0 and 4.0, as used in Internet Explorer, allows remote attackers to obtain sensitive information from another domain via a crafted XML document, related to improper error checks for external DTDs, aka "MSXML DTD Cross-Domain Scripting Vulnerability."

Unspecified vulnerability in the Simba MDrmSap ActiveX control in mdrmsap.dll in SAP SAPgui allows remote attackers to execute arbitrary code via unknown vectors involving instantiation by Internet Explorer.

The PMA_escapeJsString function in libraries/js_escape.lib.php in phpMyAdmin before 2.11.9.2, when Internet Explorer is used, allows remote attackers to bypass cross-site scripting (XSS) protection mechanisms and conduct XSS attacks via a NUL byte inside a "</script" sequence.

Microsoft Internet Explorer allows web sites to set cookies for domains that have a public suffix with more than one dot character, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session, aka "Cross-Site Cooking." NOTE: this issue may exist because of an insufficient fix for CVE-2004-0866.

Cross-site scripting (XSS) vulnerability in FreeStyle Wiki 3.6.2 and earlier, and 3.6.3 dev3 and earlier development versions, when Internet Explorer is used, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, a different issue than CVE-2005-1799.

Argument injection vulnerability in XChat 2.8.7b and earlier on Windows, when Internet Explorer is used, allows remote attackers to execute arbitrary commands via the --command parameter in an ircs:// URI.
