Description Andrej Nemec 2017-06-14 07:23:06 UTC

An exploitable vulnerability exists in the Databook loading functionality of Tablib. A yaml loaded Databook can execute arbitrary python commands resulting in command execution. An attacker can insert python into loaded yaml to trigger this vulnerability.

Statement:

Red Hat Product Security has rated this issue as having Low security impact in Red Hat OpenStack Platform.
