Aviso de seguridad de Debian

DSA-1198-1 python2.3 -- besbordamiento de búfer

Fecha del informe:

23 de oct de 2006

Paquetes afectados:

python2.3

Vulnerable:

Sí

Referencias a bases de datos de seguridad:

En el sistema de seguimiento de errores de Debian: error 391589.
En el diccionario CVE de Mitre: CVE-2006-4980.

Información adicional:

Benjamin C. Wiley Sittler descubrió que la función repr() del intérprete de Python no reservaba memoria suficiente al analizar cadenas Unicode UCS-4, lo que podía conducir a la ejecución de código arbitrario mediante un desbordamiento de búfer.

Para la distribución estable (sarge), este problema se ha corregido en la versión 2.3.5-3sarge2. Debido a problemas en la compilación, esta actualización carece de paquetes compilados para las arquitecturas Alpha y Sparc. Cuando se resuelvan, se publicarán los binarios para estas arquitecturas.

Para la distribución inestable (sid), este problema se ha corregido en la versión 2.3.5-16.

Le recomendamos que actualice los paquetes de Python 2.3.

Arreglado en:

Debian GNU/Linux 3.1 (sarge)
