Microsoft Internet Explorer 8 and earlier, and Internet Explorer 9 beta, does not properly restrict cross-zone drag-and-drop actions, which allows user-assisted remote attackers to read cookie files via vectors involving an IFRAME element with a SRC attribute containing a file: URL, as demonstrated by a Facebook game, related to a "cookiejacking" issue.
Microsoft Internet Explorer 6 through 9, and 10 Consumer Preview, allows remote attackers to bypass Protected Mode or cause a denial of service (memory corruption) by leveraging access to a Low integrity process, as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012.
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 MSN Messenger 9.0 and Internet Explorer 6.0 allows remote attackers to cause a denial of service (crash) via an image with an ICC Profile with a large Tag Count.
Cross-zone scripting vulnerability in the Print Table of Links feature in Internet Explorer 6.0, 7.0, and 8.0b allows user-assisted remote attackers to inject arbitrary web script or HTML in the Local Machine Zone via an HTML document with a link containing JavaScript sequences, which are evaluated by a resource script when a user prints this document.
Microsoft Internet Explorer 6 through 6.0.2900.2180, and 7.0.6000.16711, allows remote attackers to cause a denial of service (CPU consumption) via an automatically submitted form containing a KEYGEN element, a related issue to CVE-2009-1828.
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.
Cross-site scripting (XSS) vulnerability in HP Operations Orchestration before 9.0, when Internet Explorer 6.0 is used, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.4, when Internet Explorer 6 or earlier is used, allows remote attackers to inject arbitrary web script or HTML via an uploaded file accessed with a dangerous extension such as .html located before a ? (question mark) in a query string, in conjunction with a modified URI path that has a %2E sequence in place of the . (dot) character. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-1578.
