En el diccionario CVE de Mitre: CVE-2005-3191, CVE-2005-3192, CVE-2005-3193, CVE-2005-2097, CVE-2005-3624, CVE-2005-3625, CVE-2005-3626, CVE-2005-3627, CVE-2005-3628.

Información adicional:

«infamous41md» y Chris Evans descubrieron varios desbordamientos de buffer con base en la pila en xpdf, la suite para el formato de documento portable (PDF), que también estaban presentes en libextractor, una biblioteca para extraer metadatos arbitrarios desde archivos, y que podía conducir a la denegación de servicios por caída de la aplicación o, posiblemente, a la ejecución de código arbitrario.

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

Para la distribución estable (sarge), estos problemas se han corregido en la versión 0.4.2-2sarge2.

Para la distribución inestable (sid), estos problemas se corregirán pronto.

Le recomendamos que actualice los paquetes de libextractor.

Arreglado en:

Debian GNU/Linux 3.1 (sarge)
