Vulnerabilidades

The Python client in Apache Qpid before 2.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

The serializing/deserializing functions in the qpid::framing::Buffer class in Apache Qpid 0.20 and earlier allow remote attackers to cause a denial of service (assertion failure and daemon exit) via unspecified vectors. NOTE: this issue could also trigger an out-of-bounds read, but it might not trigger a crash.

Integer overflow in the qpid::framing::Buffer::checkAvailable function in Apache Qpid 0.20 and earlier allows remote attackers to cause a denial of service (crash) via a crafted message, which triggers an out-of-bounds read.

The AMQP type decoder in Apache Qpid 0.20 and earlier allows remote attackers to cause a denial of service (memory consumption and server crash) via a large number of zero width elements in the client-properties map in a connection.start-ok message.

The default configuration for Apache Qpid 0.20 and earlier, when the federation_tag attribute is enabled, accepts AMQP connections without checking the source user ID, which allows remote attackers to bypass authentication and have other unspecified impact via an AMQP request.

Apache Qpid 0.17 and earlier does not properly restrict incoming client connections, which allows remote attackers to cause a denial of service (file descriptor consumption) via a large number of incomplete connections.

Apache QPID 0.14, 0.16, and earlier uses a NullAuthenticator mechanism to authenticate catch-up shadow connections to AMQP brokers, which allows remote attackers to bypass authentication.

Apache Qpid 0.12 does not properly verify credentials during the joining of a cluster, which allows remote attackers to obtain access to the messaging functionality and job functionality of a cluster by leveraging knowledge of a cluster-username.

The SessionAdapter::ExchangeHandlerImpl::checkAlternate function in broker/SessionAdapter.cpp in the C++ Broker component in Apache Qpid before 0.6, as used in Red Hat Enterprise MRG before 1.3 and other products, allows remote authenticated users to cause a denial of service (NULL pointer dereference, daemon crash,…

The Cluster::deliveredEvent function in cluster/Cluster.cpp in Apache Qpid, as used in Red Hat Enterprise MRG before 1.3 and other products, allows remote attackers to cause a denial of service (daemon crash and cluster outage) via invalid AMQP data.

sys/ssl/SslSocket.cpp in qpidd in Apache Qpid, as used in Red Hat Enterprise MRG before 1.2.2 and other products, when SSL is enabled, allows remote attackers to cause a denial of service (daemon outage) by connecting to the SSL port but not participating in an SSL handshake.
