Scroller Redhat
An update regarding security for jq in Red Hat OpenStack version 8.0 has been released, tackling a moderate severity vulnerability that has the potential to allow code execution.
An update for jq is now available for Red Hat OpenStack Platform 8.0 (Liberty)

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

jq is a lightweight and flexible command-line JSON processor. jq is like sed for JSON data. You can use it to slice, filter, map, or transform structured data with the same ease that sed, awk, grep, or similar applications allow you to manipulate text.
Security Fix(es):
* A heap-based buffer overflow flaw was found in jq's tokenadd() function. By tricking a victim into processing a specially crafted JSON file, an attacker could use this flaw to crash jq or, potentially, execute arbitrary code on the victim's system. (CVE-2015-8863)
