**Use Microsoft Outlook to reduce the risk of users opening RTF Files from unknown or untrusted sources** To help protect against this vulnerability, we recommend users read email messages in plain text format. For guidance on how to configure Microsoft Outlook to read all standard mail in plain text, please refer to Read email messages in plain text. **Impact of workaround:** Email messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. In addition, the following behavior may be experienced: * The changes are applied to the preview pane and to open messages. * Pictures become attachments so that they are not lost. * Because the message is still in Rich Text or HTML format in the store, the object model (custom code solutions) may behave unexpectedly.
**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.
**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.
**According to the CVSS metric, successful exploitation of this vulnerability has a high impact on availability (A:H). What does that mean for this vulnerability??** An attacker can send specially crafted packets which could impact availability of the service resulting in Denial of Service (DoS).
**Are there any additional steps that I need to follow to be protected from this vulnerability?** The changes to address this vulnerability updated Virtual Secure Mode components. The policy described in Guidance for blocking rollback of Virtualization-based Security (VBS) related security updates has been updated to account for the latest changes. If you deployed this policy, then you'll need to redeploy using the updated policy.
**How could an attacker exploit this vulnerability?** An attacker could exploit this vulnerability by tricking a user into sending a request to a malicious server. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.
**What privileges could an attacker gain with a successful exploitation?** An attacker who successfully exploited this vulnerability could gain unauthorized access to system resources, potentially allowing them to perform actions with the same privileges as the compromised process. This could lead to further system compromise and unauthorized actions within the network.
**How could an attacker exploit this vulnerability?** An attacker could exploit this vulnerability by tricking a user into sending a request to a malicious server. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.
