Comment 1 Guilherme de Almeida Suckevicz 2019-11-05 18:09:00 UTC 
Created oniguruma tracking bugs for this issue:

Affects: epel-7 [bug 1768999]
Affects: fedora-all [bug 1768998]
Affects: openstack-rdo [bug 1769000]
Comment 2 Mark Cooper 2019-11-15 04:57:37 UTC 
The following containers are packaged with OpenShift 4.x and contain a vulnerable version of oniguruma (5.9.x):
 - openshift4/ose-metering-hadoop
 - openshift4/ose-metering-hive
 - openshift4/ose-metering-presto

However, these containers include oniguruma but do not use it. This includes faq and jq which may use oniguruma, and are included within the containers but likewise, are unused.
Comment 11 Marco Benatto 2019-11-22 21:09:29 UTC 
There's an issue on Oniguruma library when compiling regular expressions to binary code. During compilation phase it tries to optimize the expression by calling the function optimize_nodes(), this function is recursive however the recursion is not controlled. An attack may leverage this issue by crafting a regular expression which trigger many recursion levels or an infinite recursion of optimize_nodes() leading to a stack overflow resulting in stack corruption and DoS.
