DSA-821-1 python2.3 -- desbordamiento de entero

Fecha del informe:
28 de sep de 2005
Paquetes afectados:
python2.3
Vulnerable:
Referencias a bases de datos de seguridad:
En el sistema de seguimiento de errores de Debian: error 324531.
En la base de datos de Bugtraq (en SecurityFocus): Id. en BugTraq 14620.
En el diccionario CVE de Mitre: CVE-2005-2491.
Información adicional:

Se ha detectado un desbordamiento de entero, con el consiguiente desbordamiento de buffer, en PCRE, la biblioteca de expresiones regulares compatibles de Perl, que permitía que un atacante ejecutase código arbitrario y que también está presente en Python. Para sacar provecho de esta vulnerabilidad era necesario que un atacante especificase la expresión regular que se fuese a usar.

La distribución estable anterior (woody) no contiene los paquetes de python2.3.

Para la distribución estable (sarge), este problema se ha corregido en la versión 2.3.5-3sarge1.

Para la distribución inestable (sid), este problema se ha corregido en la versión 2.3.5-8.

Le recomendamos que actualice los paquetes de python2.3.

Arreglado en:

Debian GNU/Linux 3.1 (sarge)
