CVE-2013-0722: Buffer Overflow

First published: Thu Jan 10 2013(Updated: )

A stack-based buffer overflow was reported [1],[2] 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. This has not yet been corrected upstream, but a proposed patch is available [3]. The initial report [1] indicates that this was given the name <a href="https://access.redhat.com/security/cve/CVE-2012-0722">CVE-2012-0722</a>.
