Aviso de seguridad de Debian
DSA-197-1 courier -- desbordamiento de búfer
- Fecha del informe:
- 15 de nov de 2002
- Paquetes afectados:
- courier
- Vulnerable:
- Sí
- Referencias a bases de datos de seguridad:
- En el diccionario CVE de Mitre: CVE-2002-1311.
- Información adicional:
-
Se ha descubierto un problema en el paquete Courier sqwebmail, un programa CGI para permitir acceso autentificado a buzones de correo locales. El programa no liberaba los permisos lo suficientemente rápido al inicio bajo ciertas circunstancias, por lo que un shell local podía ejecutar el binario sqwebmail y arreglárselas para leer un archivo cualquiera del sistema de archivos local.
Este problema se ha corregido en la versión 0.37.3-2.3 para la distribución estable actual (woody) y en la versión 0.40.0-1 para la distribución inestable (sid). La distribución estable anterior (potato) no contiene los paquetes de Courier sqwebmail. Los paquetes
courier-ssltampoco están afectados, pues no exponen ningún paquete sqwebmail.Le recomendamos que actualice el paquete sqwebmail inmediatamente.
- Arreglado en:
-
