It was discovered that the Qpid daemon did not allow the number of connections from clients to be restricted. A malicious client could use this flaw to open an excessive amount of connections, preventing other legitimate clients from establishing a connection to qpidd. To address CVE-2012-2145, new qpidd configuration options were introduced: max-negotiate-time defines the time during which initial protocol negotiation must succeed, connection-limit-per-user and connection-limit-per-ip can be used to limit the number of connections per user and client host IP.
