It was found that Satellite 5 configured with SSL/TLS for the PostgreSQL backend failed to correctly validate X.509 server certificate host name fields. A man-in-the-middle attacker could use this flaw to spoof a PostgreSQL server using a specially crafted X.509 certificate.

A flaw was found in Spacewalk-backend. This information disclosure vulnerability occurs when a system registration XML-RPC call fails, causing cleartext user passwords to be included in error messages. Remote administrators can exploit this by reading server logs and emails, leading to the unauthorized disclosure of user passwords.

spacewalk-backend in Red Hat Network Satellite 5.4 on Red Hat Enterprise Linux 6 does not properly authorize or authenticate uploads to the NULL organization when modwsgi is used, which allows remote attackers to cause a denial of service (/var partition disk consumption and failed updates) via a large number of package uploads.
