ROSLYN.SECURITY.CA5362 : Potential reference cycle in deserialized object graph (C#)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

ROSLYN.SECURITY.CA5362 : Potential reference cycle in deserialized object graph (C#)

Summary

Review code that processes untrusted deserialized data for handling of unexpected reference cycles. An unexpected reference cycle should not cause the code to enter an infinite loop. Otherwise, an unexpected reference cycle can allow an attacker to DOS or exhaust the memory of the process when deserializing untrusted data.

This check corresponds to Roslyn rule CA5362. For full rule details, see the Microsoft website: CA5362.
