Descriptions

keepalived 2.0.8 didn't check for existing plain files when writing data to a temporary file upon a call to PrintData or PrintStats. If a local attacker had previously created a file with the expected name (e.g., /tmp/keepalived.data or /tmp/keepalived.stats), with read access for the attacker and write access for the keepalived process, then this potentially leaked sensitive information.

keepalived 2.0.8 no verificaba los archivos planos existentes al escribir datos en un archivo temporal al llamar a PrintData o PrintStats. Si un atacante local hubiera creado previamente un archivo con el nombre esperado (por ejemplo, /tmp/keepalived.data o /tmp/keepalived.stats), con acceso de lectura para el atacante y acceso de escritura para el proceso keepalived, entonces esto podría filtrar información sensible.
