Upstream ticket: https://rt.perl.org/Public/Bug/Display.html?id=133204 Acknowledgments: Name: the Perl project Upstream: Jayakrishna Menon Created perl tracking bugs for this issue: Affects: fedora-all [bug 1654918] Statement: This vulnerability is present in versions of perl included with Red Hat Virtualization Hypervisor and Management Appliance, however it is not exposed in any meaningful way. Perl is only included in these images as a dependency of components which do not manipulate ENV, and are not exposed to user input. A future update may address this issue. This issue has been addressed in the following products: Red Hat Software Collections for Red Hat Enterprise Linux 7 Red Hat Software Collections for Red Hat Enterprise Linux 7.4 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.5 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.6 EUS Via RHSA-2019:0001 https://access.redhat.com/errata/RHSA-2019:0001 This issue has been addressed in the following products: Red Hat Software Collections for Red Hat Enterprise Linux 7 Red Hat Software Collections for Red Hat Enterprise Linux 7.4 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.5 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.6 EUS Red Hat Software Collections for Red Hat Enterprise Linux 6 Via RHSA-2019:0010 https://access.redhat.com/errata/RHSA-2019:0010 This issue has been addressed in the following products: Red Hat Enterprise Linux 7 Via RHSA-2019:0109 https://access.redhat.com/errata/RHSA-2019:0109 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 environment variables which could expose this flaw. I have not filed trackers as these images will inherit the existing perl fixes next time they are respun.
