Ettercap through 0.8.5.1 contains a heap out-of-bounds read vulnerability in dissector_mountd() in src/dissectors/ec_mountd.c that validates RPC credential and directory lengths independently rather than against the packet end. Network-adjacent attackers can send a crafted MOUNT MNT call to read up to 100 bytes past the heap buffer, leaking memory to the console and logs.
With curated Threat Intelligence, you can see which vulnerabilities truly put you at risk, prioritize what matters most, and act before attackers do.
