CVE-2020-1548
Status: ModifiedMedium (5.5)—
An information disclosure vulnerability exists when the Windows WaasMedic Service improperly handles memory. To exploit this vulnerability, an attacker would first have to gain execution on the victim system. An attacker could then run a specially crafted application to improperly disclose memory. The security update addresses the vulnerability by correcting how the Windows WaasMedic Service handles memory.
