CVE-2018-8360 — .NET Framework Information Disclosure Vulnerability
Important
2018-08 archive
Executive Summary
An information disclosure vulnerability exists in Microsoft .NET Framework that could allow an attacker to access information in multi-tenant environments. The vulnerability is caused when .NET Framework is used in high-load/high-density network connections where content from one stream can blend into another stream. To exploit the vulnerability, an attacker who can access one tenant in a high-load/high-density environment could potentially trigger multi-tenanted data exposure from one customer to another. The security update addresses the vulnerability by correcting the way .NET Framework handles high-load/high-density network connections.
