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.
Buffer overflow in the JPEG (JPG) parsing engine in the Microsoft Graphic Device Interface Plus (GDI+) component, GDIPlus.dll, allows remote attackers to execute arbitrary code via a JPEG image with a small JPEG COM field length that is normalized to a large integer length before a memory copy operation.
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.
Argument injection vulnerability in Microsoft Outlook 2002 does not sufficiently filter parameters of mailto: URLs when using them as arguments when calling OUTLOOK.EXE, which allows remote attackers to use script code in the Local Machine zone and execute arbitrary programs.
Microsoft Outlook 2002 does not properly handle requests to encrypt email messages with V1 Exchange Server Security certificates, which causes Outlook to send the email in plaintext, aka "Flaw in how Outlook 2002 handles V1 Exchange Server Security Certificates could lead to Information Disclosure."
Microsoft Outlook 2002 allows remote attackers to embed bypass the file download restrictions for attachments via an HTML email message that uses an IFRAME to reference malicious content.
Microsoft Outlook 2002 allows remote attackers to execute arbitrary JavaScript code, even when scripting is disabled, via an "about:" or "javascript:" URI in the href attribute of an "a" tag.
Microsoft Outlook 2002 allows remote attackers to cause a denial of service (repeated failure) via an email message with a certain invalid header field that is accessed using POP3, IMAP, or WebDAV, aka "E-mail Header Processing Flaw Could Cause Outlook 2002 to Fail."
An interaction between Windows Media Player (WMP) and Outlook 2002 allows remote attackers to bypass Outlook security settings and execute Javascript via an IFRAME in an HTML email message that references .WMS (Windows Media Skin) or other WMP media files, whose onload handlers execute the player.LaunchURL() Javascript function.
Microsoft Outlook 2000 and 2002, when configured to use Microsoft Word as the email editor, does not block scripts that are used while editing email messages in HTML or Rich Text Format (RTF), which could allow remote attackers to execute arbitrary scripts via an email that the user forwards or replies to.
