Ettercap through 0.8.4.1 contains a heap buffer overflow vulnerability in gg_get_version() in src/dissectors/ec_gg.c that writes up to 44 bytes into a 30-byte allocation. Remote attackers can send Gadu-Gadu traffic on TCP port 8074 with a crafted version field through a monitored network to corrupt heap memory in the Ettercap process, which normally runs as root.
