CVE-2019-1205

Technical Description

A remote code execution vulnerability exists in Microsoft Word 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. 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 Word software.

Two possible email attack scenarios exist for this vulnerability:

With the first email attack scenario, an attacker could send a specially crafted email message to the user and wait for the user to click on the message. When the message renders via Microsoft Word in the Outlook Preview Pane, an attack could be triggered.

With the second scenario, an attacker could attach a specially crafted file to an email, send it to a user, and convince them to open it.
