CVE-2012-0950

Estado: ModificadaMedia (5)—

El gancho Apport (DistUpgradeApport.py) en Update Manager, como el usado por Ubuntu v12.04 LTS, v11.10, y v11.04, carga el directorio /var/log/dist-upgrade al informar de los fallos a Launchpad, lo que permite a atacantes remotos leer las credenciales del repositorio mediante la visualización de un informe de error público. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2012-0949.
