Description Adam Mariš 2017-02-03 15:20:54 UTC
Integer overflow in ZeroMQ parser in print-zeromq.c:zmtp1_print_frame() was found that may cause an infinite loop. This issue can be be exploited either locally by making the target system to decode crafted .pcap file using tcpdump, or remotely by sending crafted packets to the network segment where the target system is running tcpdump decoding the live packet capture.
