Apache CXF before 2.6.14 and 2.7.x before 2.7.11 allows remote attackers to cause a denial of service (/tmp disk consumption) via a large invalid SOAP message.

Apache CXF before 2.6.14 and 2.7.x before 2.7.11 allows remote attackers to cause a denial of service (memory consumption) via a large request with the Content-Type set to text/html to a SOAP endpoint, which triggers an error.

Apache CXF before 2.5.9, 2.6.x before 2.6.6, and 2.7.x before 2.7.3, when the plaintext UsernameToken WS-SecurityPolicy is enabled, allows remote attackers to bypass authentication via a security header of a SOAP request containing a UsernameToken element that lacks a password child element.

Apache CXF 2.4.5 through 2.4.7, 2.5.1 through 2.5.3, and 2.6.x before 2.6.1, does not properly enforce child policies of a WS-SecurityPolicy 1.1 SupportingToken policy on the client side, which allows remote attackers to bypass the (1) AlgorithmSuite, (2) SignedParts, (3) SignedElements, (4) EncryptedParts, and (5) EncryptedElements policies.

Apache CXF 2.4.x before 2.4.8, 2.5.x before 2.5.4, and 2.6.x before 2.6.1, when a Supporting Token specifies a child WS-SecurityPolicy 1.1 or 1.2 policy, does not properly ensure that an XML element is signed or encrypted, which has unspecified impact and attack vectors.
