CVE-2020-1145: Microsoft Windows 10

Medium severity, CVSS 5.5. EPSS: 2% chance of exploitation in the next 30 days.

An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory, allowing an attacker to retrieve information from a targeted system. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The security update addresses the vulnerability by correcting how GDI handles memory addresses.

Affected products

  • Microsoft Windows 10: version 1903 only; version 1909 only
  • Microsoft Windows Server 2016: version 1903 only; version 1909 only
