ettercap: code execution

From the Red Hat bugzilla entry:

A stack-based buffer overflow was reported in Ettercap <= 0.7.5.1. A boundary error within the scan_load_hosts() function (in src/ec_scan.c), when parsing entries from a hosts list, could be exploited to cause a stack-based buffer overflow via an overly long entry. In order to exploit this, a user must be tricked into loading a malicious host file.
