Description Martin Prpič 2016-04-29 05:18:28 EDT

It was found that authentication against the Cyrus SASL library would permit a remote user to specify a realm string which is a prefix of the expected realm string. Consequently, a user who has valid credentials to a realm, whose name is a prefix of the repository's realm, would be able to successfully authenticate to the repository.
