Published Feb 28, 2016

Updated

The dissectllrpparameters function in epan/dissectors/packet-llrp.c in the LLRP dissector in Wireshark 1.12.x before 1.12.10 and 2.0.x before 2.0.2 does not limit the recursion depth, which allows remote attackers to cause a denial of service (memory consumption or application crash) via a crafted packet.
