<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. 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.</p>
<p>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.</p>
<p>Note that where severity is indicated as Critical in the Affected Products table, the Preview Pane is an attack vector.</p>

<p>A denial of service vulnerability exists in Microsoft Outlook software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could cause a remote denial of service against a system.</p>
<p>Exploitation of the vulnerability requires that a specially crafted email be sent to a vulnerable Outlook server.</p>

A remote code execution vulnerability exists in Microsoft Outlook software when it fails to properly handle objects in memory, aka 'Microsoft Outlook Remote Code Execution Vulnerability'.CVE-2020-1493microsoft365_apps+7EPSS score7.30%
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.

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.

A remote code execution vulnerability exists when Microsoft Office improperly loads arbitrary type libraries, aka 'Microsoft Office Remote Code Execution Vulnerability'. This CVE ID is unique from CVE-2020-0991.CVE-2020-0696microsoftmicrosoft office+4EPSS score4.99%
A security feature bypass vulnerability exists in Microsoft Outlook software when it improperly handles the parsing of URI formats, aka 'Microsoft Outlook Security Feature Bypass Vulnerability'.CVE-2020-17119microsoft365_apps+8EPSS score4.02%
Microsoft Outlook Information Disclosure VulnerabilityCVE-2001-1088microsoftoutlook+1EPSS score19.71%
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.CVE-2001-0322microsoftinternet_explorer+2EPSS score20.95%
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.
