Doc Text:
A vulnerability was discovered in the OpenStack Orchestration service (heat), where a specially formatted template could be used to trick the heat-engine service into opening a local file. Although the file contents are never disclosed to the end user, an OpenStack-authenticated attacker could use this flaw to cause a denial of service or determine whether a given file name is present on the server.

Description Adam Mariš 2016-01-13 16:49:00 UTC 
A vulnerability in Heat template validation was reported. By referencing a local file like /dev/zero, an authenticated user may trick the heat engine service to load arbitrary local file content resulting in a Denial of Service attack through memory exhaustion. Note that the file content is not written back to the user, though the user can determine if a file exists and if it is readable by heat-engine.

Affects versions <=2015.1.2, ==5.0.0. All Heat setups are affected.
