A flaw was found in the Undertow AJP connector. Malicious requests and abrupt connection closes could be triggered by an attacker using query strings with non-RFC compliant characters resulting in a denial of service. The highest threat from this vulnerability is to system availability. This affects Undertow 2.1.5.SP1, 2.0.33.SP2, and 2.2.3.SP1.

Red Hat OpenShift Enterprise before 2.2 does not properly restrict access to gears, which allows remote attackers to access the network resources of arbitrary gears via unspecified vectors.

Red Hat OpenShift Enterprise before 2.2 allows local users to obtain IP address and port number information for remote systems by reading /proc/net/tcp.
