Descriptions

Buffer overflow in Mutt 1.4.2 might allow local users to execute arbitrary code via "&" characters in the GECOS field, which triggers the overflow during alias expansion.

Desbordamiento de búfer en Mutt 1.4.2 podría permitir a usuarios locales ejecutar código de su elección mediante caracteres "&" en el campo GECOS, lo cual dispara el desbordamiento durante una expansión de alias.

A flaw in the way mutt processed certain APOP authentication requests was discovered. By sending certain responses when mutt attempted to authenticate again an APOP server, a remote attacker could possibly obtain certain portions of the user's authentication credentials. A flaw in how mutt handled certain characters in gecos fields could lead to a buffer overflow. A local user able to give themselves a carefully crafted Real Name could potentially execute arbitrary code if a victim used mutt to expand the attacker's alias.
