Microsoft Internet Explorer 6.0 SP1 allows remote attackers to cause a denial of service (crash) by creating a DHTML link that uses the AnchorClick "A" object with a blank href attribute.

Microsoft Internet Explorer 5.22, and other 5 through 6 SP1 versions, sends Referer headers containing https:// URLs in requests for http:// URLs, which allows remote attackers to obtain potentially sensitive information by reading Referer log data.

Internet Explorer 5.01 through 6.0 does not properly handle object tags returned from a Web server during XML data binding, which allows remote attackers to execute arbitrary code via an HTML e-mail message or web page.

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).

Buffer overflow in the BR549.DLL ActiveX control for Internet Explorer 5.01 SP3 through 6.0 SP1 allows remote attackers to execute arbitrary code.

Internet Explorer 5.01 SP3 through 6.0 SP1 allows remote attackers to access and execute script in the My Computer domain using the browser cache via crafted Content-Type and Content-Disposition headers, aka the "Browser Cache Script Execution in My Computer Zone" vulnerability.

Internet Explorer 5.01 SP3 through 6.0 SP1 does not properly determine object types that are returned by web servers, which could allow remote attackers to execute arbitrary code via an object tag with a data parameter to a malicious file hosted on a server that returns an unsafe Content-Type, aka the "Object Type" vulnerability.

Buffer overflow in Internet Explorer 6 SP1 for certain languages that support double-byte encodings (e.g., Japanese) allows remote attackers to execute arbitrary code via the Type property of an Object tag, a variant of CVE-2003-0344.

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.

Buffer overflow in URLMON.DLL in Microsoft Internet Explorer 5.01, 5.5 and 6.0 allows remote attackers to execute arbitrary code via an HTTP response containing long values in (1) Content-type and (2) Content-encoding fields.

The file upload control in Microsoft Internet Explorer 5.01, 5.5, and 6.0 allows remote attackers to automatically upload files from the local system via a web page containing a script to upload the files.

Microsoft Internet Explorer 5.01, 5.5 and 6.0 does not properly check parameters that are passed during third party rendering, which could allow remote attackers to execute arbitrary web script, aka the "Third Party Plugin Rendering" vulnerability, a different vulnerability than CVE-2003-0233.

Microsoft Internet Explorer 5.01, 5.5 and 6.0 does not properly check the Cascading Style Sheet input parameter for Modal dialogs, which allows remote attackers to read files on the local system via a web page containing script that creates a dialog and then accesses the target files, aka "Modal Dialog script execution."

Heap-based buffer overflow in plugin.ocx for Internet Explorer 5.01, 5.5 and 6.0 allows remote attackers to execute arbitrary code via the Load() method, a different vulnerability than CVE-2003-0115.

Microsoft Internet Explorer 5.5 and 6.0 allows remote attackers to bypass the cross-domain security model to run malicious script or arbitrary programs via dialog boxes, aka "Improper Cross Domain Security Validation with dialog box."

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."

Microsoft Internet Explorer 5.0 through 6.0 allows remote attackers to cause a denial of service (crash) via an object of type "text/html" with the DATA field that identifies the HTML document that contains the object, which may cause infinite recursion.

Microsoft Internet Explorer 6.0, when handling an expired CA-CERT in a webserver's certificate chain during a SSL/TLS handshake, does not prompt the user before searching for and finding a newer certificate, which may allow attackers to perform a man-in-the-middle attack. NOTE: it is not clear whether this poses a vulnerability.

Internet Explorer 6.0 does not warn users when an expired certificate authority (CA) certificate is submitted to the user and a newer CA certificate is in the user's local repository, which could allow remote attackers to decrypt web sessions via a man-in-the-middle (MITM) attack.

Internet Explorer 5.01 through 6.0 does not properly check certain parameters of a PNG file when opening it, which allows remote attackers to cause a denial of service (crash) by triggering a heap-based buffer overflow using invalid length codes during decompression, aka "Malformed PNG Image File Failure."
