DSA-1146-1 krb5 -- error de programación

Fecha del informe:

9 de ago de 2006

Paquetes afectados:

Vulnerable:

Sí

Referencias a bases de datos de seguridad:

En el diccionario CVE de Mitre: CVE-2006-3083, CVE-2006-3084.
Notas y avisos de incidentes y vulnerabilidades en CERT: VU#580124, VU#401660.

Información adicional:

En algunas aplicaciones empaquetadas en el código fuente que se distribuye con Kerberos 5, no se verificaba si se producían correctamente las llamadas a setuid() y seteuid(), y podían fallar con algunas configuraciones de PAM. Un usuario local podía sacar provecho de alguna de estas vulnerabilidades para producir una escalada de privilegios. De momento, no se sabe de la existencia de ningún código que aproveche esta vulnerabilidad.

Para la distribución estable (sarge), estos problemas se han corregido en la versión 1.3.6-2sarge3.

Para la distribución inestable (sid), estos problemas se han corregido en la versión 1.4.3-9.

Le recomendamos que actualice los paquetes de krb5.
