A vulnerability has been found in Ettercap up to 0.8.3. The affected element is the function FUNC_DECODER of the file src/dissectors/ec_gg.c of the component GG Dissector. The manipulation of the argument gg leads to heap-based buffer overflow. The attack is possible to be carried out remotely. The complexity of an attack is rather high. The exploitability is described as difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 0.8.4 is sufficient to fix this
