Vulnerabilities (CVE)

danim.dll in Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (application crash) by accessing the Data property of a DirectAnimation DAUserData object before it is initialized, which triggers a NULL pointer dereference.

Internet Explorer 5.0 through 6.0 allows remote attackers to determine the existence of files on the client via an IMG tag with a dynsrc property that references the target file, which sets certain elements of the image object such as file size.

Internet Explorer 5.01, 5.5 and 6.0 allows remote attackers to read arbitrary files via malformed requests to the GetObject function, which bypass some of GetObject's security checks.

Unspecified vulnerability in Internet Explorer 6.0 on Microsoft Windows XP SP2 allows remote attackers to execute arbitrary code via "exceptional conditions" that trigger memory corruption, as demonstrated using an exception handler and nested object tags, a variant of CVE-2006-1992.

Microsoft Internet Explorer 6.0.2800.1106 on Microsoft Windows XP SP2, and other versions including 5.01 and 5.5, allows remote web servers to bypass zone restrictions and execute arbitrary code in the local computer zone by redirecting a function to another function with the same name, as demonstrated by SimilarMethodNameRedir, aka the "Similar Method Name Redirection Cross Domain Vulnerability."

A configuration in a web browser such as Internet Explorer or Netscape Navigator allows execution of active content such as ActiveX, Java, Javascript, etc.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by setting the Filter property of an ADODB.Recordset ActiveX object to certain values multiple times, which triggers a null dereference.

Microsoft Internet Explorer 6.0 and possibly others allows remote attackers to upload arbitrary file contents when users press a key corresponding to the JavaScript (1) event.ctrlKey or (2) event.shiftKey onkeydown event contained in a webpage. NOTE: it was reported that the vendor has disputed the severity of this issue.

Internet Explorer 5.5 and earlier executes Telnet sessions using command line arguments that are specified by the web site, which could allow remote attackers to execute arbitrary commands if the IE client is using the Telnet client provided in Services for Unix (SFU) 2.0, which creates session transcripts.

Internet Explorer 6 allows remote attackers to bypass the popup blocker via the document object model (DOM) methods in the DHTML Dynamic HTML (DHTML) Editing Component (DEC) and Javascript that calls showModalDialog.

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.

Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions and execute Javascript by setting the window's "href" to the malicious Javascript, then calling execCommand("Refresh") to refresh the page, aka BodyRefreshLoadsJPU or the "ExecCommand Cross Domain" vulnerability.

Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not intended for use within Internet Explorer, aka a variant of the "COM Object Instantiation Memory Corruption Vulnerability," a different vulnerability than CVE-2005-2127.

Microsoft Internet Explorer allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Internet Explorer to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by declaring the sourceURL attribute on an uninitialized DirectAnimation.StructuredGraphicsControl ActiveX Object, which triggers a null dereference.

Buffer overflow in Microsoft Internet Explorer 5.01, 5.5, and 6.0 allows remote attackers to execute arbitrary code via / (slash) characters in the Type property of an Object tag in a web page.

Microsoft Internet Explorer 6 and 7 Beta 2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a certain createTextRange call on a checkbox object, which results in a dereference of an invalid table pointer.

Buffer overflow in the implementation of an HTML directive in mshtml.dll in Internet Explorer 5.5 and 6.0 allows remote attackers to execute arbitrary code via a web page that specifies embedded ActiveX controls in a way that causes 2 Unicode strings to be concatenated.

Microsoft Internet Explorer 5.01, 5.5 and 6.0 allows remote attackers to execute arbitrary code under fewer security restrictions via a malformed web page that requires NetBIOS connectivity, aka "Zone Spoofing through Malformed Web Page" vulnerability.

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.

Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions and read arbitrary files by (1) modifying the createTextRange method and using CreateLink, as demonstrated using LinkillerSaveRef, LinkillerJPU, and Linkiller, or (2) modifying the createRange method and using the FIND dialog to select text, as demonstrated using Findeath, aka the "Function Pointer Override Cross Domain" vulnerability.

Microsoft Internet Explorer 4.0 through 6.0 could allow local users to differentiate between alphanumeric and non-alphanumeric characters used in a password by pressing certain control keys that jump between non-alphanumeric characters, which makes it easier to conduct a brute-force password guessing attack.

Microsoft Internet Explorer 5.01 through 6 does not always correctly identify the domain that is associated with a browser window, which allows remote attackers to obtain sensitive cross-domain information and spoof sites by running script after the user has navigated to another site.

The SmartConnect Class control allows remote attackers to cause a denial of service (Internet Explorer crash) by creating a COM object of the class associated with the control's CLSID, which is not intended for use within Internet Explorer.

HTML e-mail feature in Internet Explorer 5.5 and earlier allows attackers to execute attachments by setting an unusual MIME type for the attachment, which Internet Explorer does not process correctly.

Interpretation conflict between Internet Explorer and other web browsers such as Mozilla, Opera, and Firefox might allow remote attackers to modify the visual presentation of web pages and possibly bypass protection mechanisms such as content filters via ASCII characters with the 8th bit set, which could be stripped by Internet Explorer to render legible text, but not when using other browsers. NOTE: there has been significant discussion about this issue, and as of 20060625, it is not clear wher ... Interpretation conflict between Internet Explorer and other web browsers such as Mozilla, Opera, and Firefox might allow remote attackers to modify the visual presentation of web pages and possibly bypass protection mechanisms such as content filters via ASCII characters with the 8th bit set, which could be stripped by Internet Explorer to render legible text, but not when using other browsers. NOTE: there has been significant discussion about this issue, and as of 20060625, it is not clear where the responsibility for this issue lies, although it might be due to vagueness within the associated standards. NOTE: this might only be exploitable with certain encodings.
