Description
Ettercap through 0.8.4.1 contains an out-of-bounds read vulnerability in Parse_NTLM_Auth() in src/dissectors/ec_http.c due to unvalidated NTLM message offsets. Attackers can send a crafted HTTP Authorization header observed by Ettercap to read beyond the buffer, disclosing memory or crashing the process.
