The Microsoft Office application installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by multiple vulnerabilities:
An information disclosure vulnerability exists when Microsoft Excel improperly discloses the contents of its memory. An attacker who exploited the vulnerability could use the information to compromise the userβs computer or data. To exploit the vulnerability, an attacker could craft a special document file and then convince the user to open it. An attacker must know the memory address location where the object was created. (CVE-2019-1446)
A remote code execution vulnerability exists in Microsoft Excel 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 current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. 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. (CVE-2019-1448)
A security feature bypass vulnerability exists in Microsoft Office software by not enforcing macro settings on an Excel document. The security feature bypass by itself does not allow arbitrary code execution. To successfully exploit the vulnerability, an attacker would have to embed a control in an Excel worksheet that specifies a macro should be run. To exploit the vulnerability, an attacker would have to convince a user to open a specially crafted file with an affected version of Microsoft Office software.
