Microsoft Internet Explorer allows remote attackers to cause a denial of service (application crash from memory consumption), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays.

Microsoft Internet Explorer 6.0 SP1 does not properly handle certain character strings in the Path attribute, which can cause it to modify cookies in other domains when the attacker's domain name is within the target's domain name or when wildcard DNS is being used, which allows remote attackers to hijack web sessions.

Microsoft Internet Explorer 6 allows remote attackers to spoof the address bar to facilitate phishing attacks via Javascript that uses an invalid URI, modifies the Location field, then uses history.back to navigate to the previous domain, aka NullyFake.

Microsoft Windows Internet Explorer 5.5 and 6.0 allows remote attackers to execute arbitrary code via an embedded script that uses Shell Helper objects and a shortcut (link) to execute the target script.

Microsoft Internet Explorer 5.0 through 6.0 allows remote attackers to bypass cross-frame scripting restrictions and capture keyboard events from other domains via an HTML document with Javascript that is outside a frameset that includes the target domain, then forcing the frameset to maintain focus. NOTE: the discloser claimed that the vendor does not categorize this as a vulnerability, but it can be used in a spoofing scenario; the discloser provides alternate scenarios. Spoofing scenarios are currently included in CVE.

Hastymail 1.0.1 and earlier (stable) and 1.1 and earlier (development) does not send the "attachment" parameter in the Content-Disposition field for attachments, which causes the attachment to be rendered inline by Internet Explorer when the victim clicks the download link, which facilitates cross-site scripting (XSS) and possibly other attacks.

Directory traversal vulnerability in Microsoft Internet Explorer 5.01, 5.5, and 6.0 allows remote malicious FTP servers to overwrite arbitrary files via .. (dot dot) sequences in filenames returned from a LIST command.

Internet Explorer 6.x allows remote attackers to install arbitrary programs via mousedown events that call the Popup.show method and use drag-and-drop actions in a popup window, aka "HijackClick 3" and the "Script in Image Tag File Download Vulnerability."

Internet Explorer 6.0 SP1 and earlier, and possibly other versions, allows remote attackers to cause a denial of service (application crash from "memory corruption") via certain malformed Cascading Style Sheet (CSS) elements that trigger heap-based buffer overflows, as demonstrated using the "<STYLE>@;/*" string, possibly due to a missing comment terminator that may cause an invalid length to trigger a large memory copy operation, aka the "CSS Heap Memory Corruption Vulnerability."

Mozilla Firefox 0.9.2 allows web sites to set cookies for country-specific top-level domains, such as .ltd.uk, .plc.uk, and .sch.uk, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session. NOTE: it was later reported that 2.x is also affected.

Microsoft Internet Explorer 6.0, Outlook 2002, and Outlook 2003 allow remote attackers to cause a denial of service (CPU consumption), if "Do not save encrypted pages to disk" is disabled, via a web site or HTML e-mail that contains two null characters (%00) after the host name.

The execCommand method in Microsoft Internet Explorer 6.0 SP2 allows remote attackers to bypass the "File Download - Security Warning" dialog and save arbitrary files with arbitrary extensions via the SaveAs command.

Internet Explorer 6.0 allows web sites to set cookies for country-specific top-level domains, such as .ltd.uk, .plc.uk, and .sch.uk, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session.

Internet Explorer in Windows XP SP2, and other versions including 5.01 and 5.5, allows remote attackers to install arbitrary programs via a web page that uses certain styles and the AnchorClick behavior, popup windows, and drag-and-drop capabilities to drop the program in the local startup folder, as demonstrated by "wottapoop.html".

Unknown versions of Internet Explorer and Outlook allow remote attackers to spoof a legitimate URL in the status bar via A HREF tags with modified "alt" values that point to the legitimate site, combined with an image map whose href points to the malicious site, which facilitates a "phishing" attack.

The WebBrowser ActiveX control, or the Internet Explorer HTML rendering engine (MSHTML), as used in Internet Explorer 6, allows remote attackers to execute arbitrary code in the Local Security context by using the showModalDialog method and modifying the location to execute code such as Javascript, as demonstrated using (1) delayed HTTP redirect operations, and an HTTP response with a Location: header containing a "URL:" prepended to a "ms-its" protocol URI, or (2) modifying the location attribute of the window, as exploited by the Download.ject (aka Scob aka Toofer) using the ADODB.Stream object.

Double free vulnerability in mshtml.dll for certain versions of Internet Explorer 6.x allows remote attackers to cause a denial of service (application crash) via a malformed GIF image.

Internet Explorer for Mac 5.2.3, Internet Explorer 6 on Windows XP, and possibly other versions, does not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.

The Windows Shell application in Windows 98, Windows ME, Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows remote attackers to execute arbitrary code by spoofing the type of a file via a CLSID specifier in the filename, as demonstrated using Internet Explorer 6.0.2800.1106 on Windows XP.

Internet Explorer 5.x and 6.0 allows remote attackers to execute arbitrary programs via a modified directory traversal attack using a URL containing ".." (dot dot) sequences and a filename that ends in "::" which is treated as a .chm file even if it does not have a .chm extension. NOTE: this bug may overlap CVE-2004-0475.
