DSA-763-1 zlib -- denegación de servicio remota

Fecha del informe:

20 de jul de 2005

Paquetes afectados:

zlib

Vulnerable:

Sí

Referencias a bases de datos de seguridad:

En el diccionario CVE de Mitre: CVE-2005-1849.

Información adicional:

Markus Oberhumer descubrió una debilidad en la forma en la que zlib, una biblioteca que se usa para comprimir y descomprimir archivos, gestionaba la entrada no válida. Esta debilidad podía provocar que los programas que usaran zlib cayesen cuando fueran a abrir un archivo no válido.

Este problema no afecta a la distribución estable anterior (woody).

Para la distribución estable actual (sarge), este problema se ha corregido en la versión 1.2.2-4.sarge.2.

Para la distribución inestable (sid), este problema se ha corregido en la versión 1.2.3-1.

Le recomendamos que actualice el paquete zlib.

Arreglado en:

Debian GNU/Linux 3.1 (stable)
