FAQ
According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution? The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.
FAQ
According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do? For this vulnerability to be exploited, a user would need to open or otherwise process a specially crafted Enhanced Metafile (EMF) file using Microsoft Paint. This action is necessary to trigger the affected graphics functionality in the Windows component.
