Description of the Security Only update for .NET Framework 2.0 SP2 and 3.0 SP2 for Windows Server 2008 SP2 (KB 4344176)

Summary

This security update resolves an information disclosure vulnerability 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 in which 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.

This security update addresses the vulnerability by correcting the way that .NET Framework handles high-load/high-density network connections.

To learn more about this vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2018-8360.
