CVE-2020-0877: 
vulnerability analysis and mitigation

An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory, identified as CVE-2020-0877. This vulnerability is unique from CVE-2020-0788 and CVE-2020-0887, affecting various versions of Microsoft Windows operating systems (MITRE, NVD).

The vulnerability has been assigned a CVSS v3.1 base score of 7.8 (HIGH) with the following vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This indicates that the vulnerability requires local access, low attack complexity, low privileges, and no user interaction, while potentially impacting confidentiality, integrity, and availability at high levels (NVD).

If successfully exploited, an attacker could gain elevated privileges on the affected system. The attacker could then gain the same user rights as the local user, with users having administrative rights being more severely impacted than those with fewer system privileges (NVD).

Microsoft has released security updates to address this vulnerability. Users should apply the appropriate security updates for their affected Windows systems through Windows Update (Microsoft Advisory).
