Descriptions

Buffer overflow in the SIEVE script component (sieve/script.c), as used in cyrus-imapd in Cyrus IMAP Server 2.2.13 and 2.3.14, and Dovecot 1.0 before 1.0.4 and 1.1 before 1.1.7, allows local users to execute arbitrary code and read or modify arbitrary messages via a crafted SIEVE script, related to the incorrect use of the sizeof operator for determining buffer length, combined with an integer signedness error.

Un desbordamiento de búfer en el componente script SIEVE (archivo sieve/script.c), tal y como es usado en cyrus-imapd en IMAP Server versiones 2.2.13 y 2.3.14, y Dovecot versiones 1.0 anteriores a 1.0.4 y versiones 1.1 anteriores a 1.1.7, de Cyrus, permite a los usuarios locales ejecutar código arbitrario y leer o modificar mensajes arbitrarios por medio de un script SIEVE diseñado, relacionado con el uso incorrecto del operador sizeof para determinar la longitud del búfer, combinado con un error de firma de enteros.
