The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in the dissector_postgresql function in dissectors/ec_postgresql.c in Ettercap before 0.8.1 allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted password length value that is inconsistent with the actual length of the password.
