Summary

A remote code execution vulnerability has been identified in Microsoft Outlook. This vulnerability arises when Outlook improperly manages objects in memory, potentially allowing an attacker to execute arbitrary code within the context of the application. An attacker exploiting this vulnerability could gain the same user privileges as the logged-in user. Successful exploitation might enable the attacker to install programs; view, change, or delete data; or create new accounts with full user rights. Mitigating this risk involves applying the latest security patches provided by Microsoft.
