Microsoft Windows COM CVE-2017-0298 Local Privilege Escalation Vulnerability

Description

Microsoft Windows is prone to a local privilege-escalation vulnerability. Successful exploits may allow an attacker to execute arbitrary code in the context of another user’s session.

Recommendations

Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
Ensure that only trusted users have local, interactive access to affected computers.

Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as non-executable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.

Updates are available. Please see the references or vendor advisory for more information.
