Microsoft Internet Explorer 6.0

Heap-based buffer overflow in Internet Explorer 6 allows remote attackers to execute arbitrary code via long (1) SRC or (2) NAME attributes in IFRAME, FRAME, and EMBED elements, as originally discovered using the mangleme utility, aka "the IFRAME vulnerability" or the "HTML Elements Vulnerability."

Microsoft Internet Explorer 6.0 and 7.0 allows remote attackers to fill Zones with arbitrary domains using certain metacharacters such as wildcards via JavaScript, which results in a denial of service (website suppression and resource consumption), aka "Internet Explorer Zone Domain Specification Dos and Page Suppressing". NOTE: this issue has been disputed by a third party, who states that the zone settings cannot be manipulated

mshtml.dll in Microsoft Windows XP, Server 2003, and Internet Explorer 6.0 SP1 allows attackers to cause a denial of service (access violation) by causing mshtml.dll to process button-focus events at the same time that a document is reloading, as seen in Microsoft Office InfoPath 2003 by repeatedly clicking the "Delete" button in a repeating section in a form. NOTE: the normal operation of InfoPath appears to involve a local user without any privilege boundaries, so this might not be a vulnerability in InfoPath. If no realistic scenarios exist for this problem in other products, then perhaps it should be excluded from CVE.

Heap-based buffer overflow in the DirectAnimation Path Control (DirectAnimation.PathControl) COM object (daxctle.ocx) for Internet Explorer 6.0 SP1, on Chinese and possibly other Windows distributions, allows remote attackers to execute arbitrary code via unknown manipulations in arguments to the KeyFrame method, possibly related to an integer overflow, as demonstrated by daxctle2, and a different vulnerability than CVE-2006-4446.

CRLF injection vulnerability in Microsoft Internet Explorer 6.0.2800.1106 and earlier allows remote attackers to execute arbitrary FTP commands via an ftp:// URL that contains a URL-encoded newline ("%0a") before the FTP command, which causes the commands to be inserted into the resulting FTP session, as demonstrated using a PORT command.

The showHelp() function in Microsoft Internet Explorer 5.01, 5.5, and 6.0 supports certain types of pluggable protocols that allow remote attackers to bypass the cross-domain security model and execute arbitrary code, aka "Improper Cross Domain Security Validation with ShowHelp functionality."

Internet Explorer allows remote attackers to bypass zone restrictions to inject and execute arbitrary programs by creating a popup window and inserting ActiveX object code with a "data" tag pointing to the malicious code, which Internet Explorer treats as HTML or Javascript, but later executes as an HTA application, a different vulnerability than CVE-2003-0532, and as exploited using the QHosts Trojan horse (aka Trojan.Qhosts, QHosts-1, VBS.QHOSTS, or aolfix.exe).
