Summary
Ettercap through 0.8.5.1 Heap Out-of-Bounds Read via SOCKS5 Dissector
Details

Ettercap through 0.8.5.1 contains a heap out-of-bounds read vulnerability in dissector_socks() in src/dissectors/ec_socks.c that allows network-adjacent attackers to read heap memory via unchecked SOCKS5 username/password lengths. Attackers can send a crafted SOCKS5 authentication packet observed by Ettercap to read up to 255 bytes past the heap buffer, disclosing memory printed and logged as captured credentials.
