https://notcve.org/view.php?id=CVE-2004-2771

The expand function in fio.c in Heirloom mailx 12.5 and earlier and BSD mailx 8.1.2 and earlier allows remote attackers to execute arbitrary commands via shell metacharacters in an email address. La función extendida en fio.c en Heirloom mailx 12.5 y anteriores y BSD mailx 8.1.2 y anteriores permite a atacantes remotos ejecutar comandos arbitrarios a través metacaracteres de shell en una dirección de correo electrónico. A flaw was found in the way mailx handled the parsing of email addresses.
