Race condition in Network Manager before 1.0.12 as packaged in Red Hat Enterprise Linux Desktop 7, Red Hat Enterprise Linux HPC Node 7, Red Hat Enterprise Linux Server 7, and Red Hat Enterprise Linux Workstation 7 allows local users to obtain sensitive connection information by reading temporary files during ifcfg and keyfile changes.

Una condición de carrera en Network Manager anterior a versión 1.0.12 como empaquetado en Red Hat Enterprise Linux Desktop 7, Red Hat Enterprise Linux HPC Node 7, Red Hat Enterprise Linux Server 7 y Red Hat Enterprise Linux Workstation 7, permite a los usuarios locales obtener información de conexión confidencial mediante la lectura de archivos temporales durante cambios de ifcfg y keyfile.

A race condition vulnerability was discovered in NetworkManager. Temporary files were created insecurely when saving or updating connection settings, which could allow local users to read connection secrets such as VPN passwords or WiFi keys.
