ZeroMQ libzmq v2_decoder Integer Overflow

An integer overflow vulnerability has been discovered in ZeroMQ libzmq library. The vulnerability is due to improper sanitization of user-supplied data passed to zmq::v2_decoder_t::size_ready function when handling ZMTP messages. A remote attacker could exploit this vulnerability by sending a specially crafted packet to the vulnerable service. Successful exploitation could result in the execution of arbitrary code in the security context of the service implementing the vulnerable library.
