En la base de datos de Bugtraq (en SecurityFocus): Id. en BugTraq 7123.
En el diccionario CVE de Mitre: CVE-2003-0028.
Notas y avisos de incidentes y vulnerabilidades en CERT: VU#516825, CA-2003-10.

Información adicional:

eEye Digital Security descubrió un desbordamiento de entero en la función xdrmem_getbytes() que también está presente en GNU libc. Esta función es parte del codificador/decodificador XDR (representación de datos externa) derivado de la implementación de RPC de Sun. Según la aplicación, esta vulnerabilidad podía causar desbordamientos de búfer y posiblemente pudiera ser explotada para ejecutar código arbitrario.

Para la distribución estable (woody), este problema se ha corregido en la versión 2.2.5-11.5.

Para la distribución estable anterior (potato), este problema se ha corregido en la versión 2.1.3-25.

Para la distribución inestable (sid), este problema se ha corregido en la versión 2.3.1-16.

Le recomendamos que actualice los paquetes de libc6.

Arreglado en:

Debian GNU/Linux 2.2 (potato)
