DSA-149-1 glibc -- desbordamiento de entero

Fecha del informe:

13 de ago de 2002

Paquetes afectados:

Vulnerable:

Sí

Referencias a bases de datos de seguridad:

En la base de datos de Bugtraq (en SecurityFocus): Id. en BugTraq 5356.
En el diccionario CVE de Mitre: CVE-2002-0391.
Notas y avisos de incidentes y vulnerabilidades en CERT: VU#192995.

Información adicional:

Se ha descubierto un error de desbordamiento de entero en la biblioteca RPC usada por GNU licb, que se deriva de la biblioteca SunRPC. Este error se podía explotar para conseguir acceso no autorizado como root a software enlazado con este código. Los paquetes de abajo también corrigen desbordamientos de enteros en el código de malloc. También contienen una corrección de Andreas Schwab para reducir linebuflen en paralelo al incrementar el puntero de búfer en el código de NSS DNS.

Este problema ha sido corredigo en la versión 2.1.3-23 de la vieja distribución estable (potato), en la versión 2.2.5-11.1 de la distribución estable actual (woody) y en la versión 2.2.5-13 para la distribución inestable (sid).

Le recomendamos que actualice los paquetes licb6 inmediatamente.

Arreglado en:

Debian GNU/Linux 2.2 (potato)
