Comment 9 Paul Harvey 2019-01-25 13:05:30 UTC
openshift-enterprise-3: notaffected. I reviewed OpenShift containers for applications with dependencies on perl and was unable to identify any where the perl interpreter would be exposed to attacker-controlled regular expressions which could expose this flaw. There is a perl dependency in our MariaDB packaging, however the only non-test related perl usage is in a backup script (mysqlhotcopy) which is not exposed to attacker-controlled regular expressions. I have not filed trackers as these images will inherit the existing perl fixes next time they are respun. See also https://access.redhat.com/articles/2803031
