Microsoft Outlook Express

The MHTML protocol handler in Microsoft Outlook Express 5.5 SP2 through Outlook Express 6 SP1 allows remote attackers to bypass domain restrictions and execute arbitrary code, as demonstrated on Internet Explorer using script in a compiled help (CHM) file that references the InfoTech Storage (ITS) protocol handlers such as (1) ms-its, (2) ms-itss, (3) its, or (4) mk:@MSITStore, aka the "MHTML URL Processing Vulnerability."

Buffer overflow in the HTML library used by Internet Explorer, Outlook Express, and Windows Explorer via the res: local resource protocol.

Heap-based buffer overflow in Microsoft Outlook Express 6 and earlier, and Windows Mail for Vista, allows remote Network News Transfer Protocol (NNTP) servers to execute arbitrary code via long NNTP responses that trigger memory corruption.

Internet Explorer 5.0 and 5.5, and Outlook Express 5.0 and 5.5, allow remote attackers to execute scripts when Active Scripting is disabled by including the scripts in XML stylesheets (XSL) that are referenced using an IFRAME tag, possibly due to a vulnerability in Windows Scripting Host (WSH).

Microsoft Outlook 98 and 2000, and Outlook Express 4.0x and 5.0x, allow remote attackers to read files on the client's system via a malformed HTML message that stores files outside of the cache, aka the "Cache Bypass" vulnerability.

Buffer overflow in the S/MIME Parsing capability in Microsoft Outlook Express 5.5 and 6.0 allows remote attackers to execute arbitrary code via a digitally signed email with a long "From" address, which triggers the overflow when the user views or previews the message.

Microsoft Outlook 8.5 and earlier, and Outlook Express 5 and earlier, with the "Automatically put people I reply to in my address book" option enabled, do not notify the user when the "Reply-To" address is different than the "From" address, which could allow an untrusted remote attacker to spoof legitimate addresses and intercept email from the client that is intended for another user.

Buffer overflow in various Microsoft applications for Macintosh allows remote attackers to cause a denial of service (crash) or execute arbitrary code by invoking the file:// directive with a large number of / characters, which affects Internet Explorer 5.1, Outlook Express 5.0 through 5.0.2, Entourage v. X and 2001, PowerPoint v. X, 2001, and 98, and Excel v. X and 2001 for Macintosh.

Outlook Express 6.0, with "Do not allow attachments to be saved or opened that could potentially be a virus" enabled, does not block email attachments from forwarded messages, which could allow remote attackers to execute arbitrary code.

Outlook Express 5.5 and 6.0 on Windows treats a carriage return ("CR") in a message header as if it were a valid carriage return/line feed combination (CR/LF), which could allow remote attackers to bypass virus protection and or other filtering mechanisms via a mail message with headers that only contain the CR, which causes Outlook to create separate headers.

Outlook Express 6.00 allows remote attackers to execute arbitrary script by embedding SCRIPT tags in a message whose MIME content type is text/plain, contrary to the expected behavior that text/plain messages will not run script.

Buffer overflow in VCard handler in Outlook 2000 and 98, and Outlook Express 5.x, allows an attacker to execute arbitrary commands via a malformed vCard birthday field.

The MHTML protocol handler in a component of Microsoft Outlook Express 5.5 SP2 and 6 through SP1, and Windows Mail, does not assign the correct Internet Explorer Security Zone to UNC share pathnames, which allows remote attackers to bypass intended access restrictions and read arbitrary files via an mhtml: URI in conjunction with a redirection, aka "URL Parsing Cross-Domain Information Disclosure Vulnerability."

Unspecified vulnerability in Microsoft Outlook Express 6 and earlier allows remote attackers to execute arbitrary code via a crafted contact record in a Windows Address Book (WAB) file.

The (1) CertGetCertificateChain, (2) CertVerifyCertificateChainPolicy, and (3) WinVerifyTrust APIs within the CryptoAPI for Microsoft products including Microsoft Windows 98 through XP, Office for Mac, Internet Explorer for Mac, and Outlook Express for Mac, do not properly verify the Basic Constraints of intermediate CA-signed X.509 certificates, which allows remote attackers to spoof the certificates of trusted sites via a man-in-the-middle attack for SSL sessions, as originally reported for Internet Explorer and IIS.

Microsoft Outlook Express 6.0 allows remote attackers to bypass intended access restrictions, load content from arbitrary sources into the Outlook context, and facilitate phishing attacks via a "BASE HREF" with the target set to "_top".

Outlook Express 6.0, when sending multipart e-mail messages using the "Break apart messages larger than" setting, leaks the BCC recipients of the message to the addresses listed in the To and CC fields, which may allow remote attackers to obtain sensitive information.

Buffer overflow in Microsoft Outlook Express 5.0, 5.5, and 6.0 allows remote attackers to cause a denial of service (crash) via a long <A HREF> link.

MSHTML.DLL HTML parser in Internet Explorer 4.0, and other versions, allows remote attackers to cause a denial of service (application crash) via a script that creates and deletes an object that is associated with the browser window object.

Outlook Express 5.01 and Internet Explorer 5.01 allow remote attackers to view a user's email messages via a script that accesses a variable that references subsequent email messages that are read by the client.

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.

Microsoft Outlook Express 5.5 and 6 allows attackers to cause a denial of service (application crash) via a malformed e-mail header.

Microsoft Outlook Express 6.0 leaks the default news server account when a user responds to a "watched" conversation thread, which could allow remote attackers to obtain sensitive information.

Microsoft Outlook client allows remote attackers to cause a denial of service by sending multiple email messages with the same X-UIDL headers, which causes Outlook to hang.

Microsoft HTML control as used in (1) Internet Explorer 5.0, (2) FrontPage Express, (3) Outlook Express 5, and (4) Eudora, and possibly others, allows remote malicious web site or HTML emails to cause a denial of service (100% CPU consumption) via large HTML form fields such as text inputs in a table cell.

Buffer overflow in Outlook Express 4.x allows attackers to cause a denial of service via a mail or news message that has a .jpg or .bmp attachment with a long file name.
