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.

In MIT krb5 release 1.4 and later, an active network attacker can alter the arguments sent by a legitimate client to RPC services protected by RPCSEC_GSS, or cause return values to be sent in plain text.
