Descriptions

lib-mail/message-header-parser.c in Dovecot 1.2.x before 1.2.17 and 2.0.x before 2.0.13 does not properly handle '\0' characters in header names, which allows remote attackers to cause a denial of service (daemon crash or mailbox corruption) via a crafted e-mail message.

lib-mail/message-header-parser.c en Dovecot v1.2.x antes de v1.2.17 y v2.0.x antes de v2.0.13 no controla correctamente los caracteres '\ 0 ' en los nombres de cabecera, lo que permite a atacantes remotos provocar una denegación de servicio (caída del demonio o la corrupción de buzón) a través de un mensaje de e-mail manipulado.
