Descriptions

BSD mailx 8.1.2 and earlier allows remote attackers to execute arbitrary commands via a crafted email address.

BSD mailx versión 8.1.2 y anteriores, permiten a atacantes remotos ejecutar comandos arbitrarios por medio de una dirección de correo electrónico diseñada.

A flaw was found in the way mailx handled the parsing of email addresses. A syntactically valid email address could allow a local attacker to cause mailx to execute arbitrary shell commands through shell meta-characters (CVE-2004-2771) and the direct command execution functionality (CVE-2014-7844).
