CVE-2019-0754 — Windows Denial of Service Vulnerability

Important CVSS 5.5 EPSS 0.01616 📢 Publicly disclosed 2019-03 archive

Executive Summary

A denial of service vulnerability exists when Windows 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.
