An attacker who successfully exploited the vulnerability could cause a target system to stop responding.\nTo 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.\nThe update addresses the vulnerability by correcting how Windows handles objects in memory.\n\n## Affected\n\n- `windows_10`\n- `windows_10 = 1607`\n- `windows_10 = 1709`\n- `windows_10 = 1803`\n- `windows_10 = 1809`\n- `windows_10 = 1903`\n- `windows_10 = 1909`\n- `windows_7`\n- `windows_8.1`\n- `windows_rt_8.1`\n- `windows_server_2008`\n- `windows_server_2008 = r2`\n- `windows_server_2012`\n- `windows_server_2012 = r2`\n- `windows_server_2016`\n- `windows_server_2019`\n- `windows_server_2019 = 1903`\n- `windows_server_2019 = 1909`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
