| 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. | |||||

| CVE-2004-0501 | 1 Microsoft | 1 Outlook | 2026-04-16 | 5.0 MEDIUM | N/A |
| Outlook 2003 allows remote attackers to bypass intended access restrictions and cause Outlook to request a URL from a remote site via an HTML e-mail message containing a Vector Markup Language (VML) entity whose src parameter points to the remote site, which could allow remote attackers to know when a message has been read, verify valid e-mail addresses, and possibly leak other information. | |||||
| CVE-2003-1378 | 1 Microsoft | 2 Outlook, Outlook Express | 2026-04-16 | 8.8 HIGH | N/A |
| Microsoft Outlook Express 6.0 and Outlook 2000, with the security zone set to Internet Zone, allows remote attackers to execute arbitrary programs via an HTML email with the CODEBASE parameter set to the program, a vulnerability similar to CAN-2002-0077. | |||||
| CVE-2006-0002 | 1 Microsoft | 3 Exchange Server, Office, Outlook | 2026-04-16 | 7.5 HIGH | N/A |
| Unspecified vulnerability in Microsoft Outlook 2000 through 2003, Exchange 5.0 Server SP2 and 5.5 SP4, Exchange 2000 SP3, and Office allows remote attackers to execute arbitrary code via an e-mail message with a crafted Transport Neutral Encapsulation Format (TNEF) MIME attachment, related to message length validation. | |||||
| CVE-2002-0481 | 1 Microsoft | 1 Outlook | 2026-04-16 | 5.1 MEDIUM | N/A |
| 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. | |||||
| CVE-2003-1048 | 1 Microsoft | 8 Internet Explorer, Outlook, Windows 98 and 5 more | 2026-04-16 | 10.0 HIGH | 7.8 HIGH |

| CVE-2004-2482 | 1 Microsoft | 1 Outlook | 2026-04-16 | 5.0 MEDIUM | N/A |
| Microsoft Outlook 2000 and 2003, when configured to use Microsoft Word 2000 or 2003 as the e-mail editor and when forwarding e-mail, does not properly handle an opening OBJECT tag that does not have a closing OBJECT tag, which causes Outlook to automatically download the URI in the data property of the OBJECT tag and might allow remote attackers to execute arbitrary code. | |||||
| CVE-2000-0567 | 1 Microsoft | 2 Outlook, Outlook Express | 2026-04-16 | 5.0 MEDIUM | N/A |
| Buffer overflow in Microsoft Outlook and Outlook Express allows remote attackers to execute arbitrary commands via a long Date field in an email header, aka the "Malformed E-mail Header" vulnerability. | |||||

| CVE-2020-1493 | 1 Microsoft | 3 365 Apps, Office, Outlook | 2026-02-23 | 4.3 MEDIUM | 5.5 MEDIUM |
| An information disclosure vulnerability exists when attaching files to Outlook messages. This vulnerability could potentially allow users to share attached files such that they are accessible by anonymous users where they should be restricted to specific users. To exploit this vulnerability, an attacker would have to attach a file as a link to an email. The email could then be shared with individuals that should not have access to the files, ignoring the default organizational setting. The security update addresses the vulnerability by correcting how Outlook handles file attachment links. | |||||
| CVE-2020-1483 | 1 Microsoft | 3 365 Apps, Office, Outlook | 2026-02-23 | 9.3 HIGH | 5.0 MEDIUM |
| A remote code execution vulnerability exists in Microsoft Outlook when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Outlook software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file. Note that where severity is indicated as Critical in the Affected Products table, the Preview Pane is an attack vector. The security update addresses the vulnerability by correcting how Outlook handles objects in memory. | |||||

| CVE-2020-16947 | 1 Microsoft | 3 365 Apps, Office, Outlook | 2026-02-23 | 9.3 HIGH | 7.5 HIGH |
| <p>A remote code execution vulnerability exists in Microsoft Outlook software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the targeted user. If the targeted user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

| CVE-2019-1218 | 1 Microsoft | 1 Outlook | 2026-02-20 | 3.5 LOW | 5.4 MEDIUM |
| A spoofing vulnerability exists in the way Microsoft Outlook iOS software parses specifically crafted email messages. An authenticated attacker could exploit the vulnerability by sending a specially crafted email message to a victim. The attacker who successfully exploited this vulnerability could then perform cross-site scripting attacks on the affected systems and run scripts in the security context of the current user. The security update addresses the vulnerability by correcting how Outlook iOS parses specially crafted email messages. | |||||
| CVE-2019-1204 | 1 Microsoft | 3 Office, Office 365 Proplus, Outlook | 2026-02-20 | 4.3 MEDIUM | 4.3 MEDIUM |
| An elevation of privilege vulnerability exists when Microsoft Outlook initiates processing of incoming messages without sufficient validation of the formatting of the messages. An attacker who successfully exploited the vulnerability could attempt to force Outlook to load a local or remote message store (over SMB). To exploit the vulnerability, the attacker could send a specially crafted email to a victim. Outlook would then attempt to open a pre-configured message store contained in the email upon receipt of the email. This update addresses the vulnerability by ensuring Office fully validates incoming email formatting before processing message content. | |||||
| CVE-2019-1200 | 1 Microsoft | 3 Office, Office 365 Proplus, Outlook | 2026-02-20 | 9.3 HIGH | 7.8 HIGH |
| A remote code execution vulnerability exists in Microsoft Outlook software when it fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. For example, the file could then take actions on behalf of the logged-on user with the same permissions as the current user. To exploit the vulnerability, a user must open a specially crafted file with an affected version of Microsoft Outlook software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file. Note that the Preview Pane is not an attack vector for this vulnerability. The security update addresses the vulnerability by correcting how Microsoft Outlook handles files in memory. | |||||
