Internet Explorer 5.01, 5.5, and 6 does not properly validate buffers when handling certain DHTML methods including the createControlRange Javascript function, which allows remote attackers to execute arbitrary code, aka the "DHTML Method Heap Memory Corruption Vulnerability."
Internet Explorer 6.0 on Windows XP SP2 allows remote attackers to spoof the domain name of a URL in a titlebar for a script-initiated popup window, which could facilitate phishing attacks.
Race condition in the memory management routines in the DHTML object processor in Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to execute arbitrary code via a malicious web page or HTML e-mail, aka "DHTML Object Memory Corruption Vulnerability".
Internet Explorer 6 on Windows XP SP2 allows remote attackers to bypass the file download warning dialog and possibly trick an unknowledgeable user into executing arbitrary code via a web page with a body element containing an onclick tag, as demonstrated using the createElement function.
Internet Explorer on Windows XP does not properly modify the "Drag and Drop or copy and paste files" setting when the user sets it to "Disable" or "Prompt," which may enable security-sensitive operations that are inconsistent with the user's intended configuration.
Internet Explorer 6.x on Windows XP SP2 allows remote attackers to execute arbitrary code, as demonstrated using a document with a draggable file type such as .xml, .doc, .py, .cdf, .css, .pdf, or .ppt, and using ADODB.Connection and ADODB.recordset to write to a .hta file that is interpreted in the Local Zone by HTML Help.
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 SP2 allows remote attackers to spoof a legitimate URL in the status bar and conduct a phishing attack via a web page that contains a BASE element that points to the legitimate site, followed by an anchor (a) element with an empty "href" attribute, and a FORM whose action points to a malicious URL, and an INPUT submit element that is modified to look like a legitimate URL.
Internet Explorer 5.01 through 6 allows remote attackers to spoof arbitrary web sites by injecting content from one window into another window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability. NOTE: later research shows that Internet Explorer 7 on Windows XP SP2 is also vulnerable.
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.
