CVE-2020-1038: Microsoft Windows 10

Medium severity, CVSS 5.5. EPSS: 1.2% chance of exploitation in the next 30 days.

A denial of service vulnerability exists when Windows Routing Utilities improperly handles objects in memory. An attacker who successfully exploited the vulnerability could cause a target system to stop responding. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to cause a target system to stop responding. The update addresses the vulnerability by correcting how Windows handles objects in memory.
