[German]ACROS Security has released a micropatch for the vulnerability CVE-2020-1281 in Windows OLE of Windows 7 and Server 2008 R2 (without ESU license).
The vulnerability CVE-2020-1281
CVE-2020-1281 is a Remote Code Execution (RCE) vulnerability because Microsoft Windows OLE does not properly validate user input. An attacker could exploit this vulnerability to execute malicious code. To exploit the vulnerability, an attacker would have to convince a user to open either a specially crafted file or program from a Web page or e-mail message.
Microsoft describes the vulnerability in this document and released security updates for Windows 7 through Windows 10 on June 9, 2020. However, users of Windows 7 SP1 and Windows Server 2008 R2 who do not have an ESU license will no longer receive the security updates that are released by Microsoft.
