=============================================================== OSSA-2016-003: Heat denial of service through template-validate ===============================================================
:Date: January 19, 2016 :CVE: CVE-2015-5295 Affects ~~~~~~~ - Heat: <=2015.1.2, ==5.0.0 Description ~~~~~~~~~~~ Steven Hardy from Red Hat reported a vulnerability in Heat template validation. 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. All Heat setups are affected.
