Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Improper certificate validation in Active Directory Federation Services (AD FS) allows an unauthorized attacker to perform spoofing over a network.

Affected packages:
- System.Security.Cryptography.Xml (release 8.0): 8.0.0 - 8.0.4; fixed 8.0.5
