DSA-819-1 python2.1 -- desbordamiento de entero

Fecha del informe:

23 de sep de 2005

Paquetes afectados:

Vulnerable:

Sí

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.

Para la distribución estable anterior (woody), este problema se ha corregido en la versión 2.1.3-3.4.

Para la distribución estable (sarge), este problema se ha corregido en la versión 2.1.3dfsg-1sarge1.

Para la distribución inestable (sid), este problema se ha corregido en la versión 2.1.3dfsg-3.

Le recomendamos que actualice los paquetes de python2.1.
