Descriptions

Multiple stack-based buffer overflows in the Sieve plugin in Dovecot 1.0 before 1.0.4 and 1.1 before 1.1.7, as derived from Cyrus libsieve, allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted SIEVE script, as demonstrated by forwarding an e-mail message to a large number of recipients, a different vulnerability than CVE-2009-2632.

Múltiples desbordamientos de búfer basados en pila en el complemento -plugin- Sieve de Dovecot v1.0 anterior a v1.0.4 y v1.1 anterior a v1.1.7, como se deriva de Cyrus libsieve, permiten a atacantes dependientes del contexto provocar una denegación de servicio (caída) y puede que ejecutar código de su elección a través de una secuencia de comandos SIEVE, como se ha demostrado reenviando un mensaje de correo a un gran número de usuarios.
