| Doc Text: |
It was found that Node.js was using a non-randomized seed when populating hash tables. An attacker, able to supply a large number of inputs, could send specially crafted entries to the Node.js application, maximizing hash collisions to trigger an excessive amount of CPU usage, resulting in a denial of service.

Created nodejs tracking bugs for this issue: Affects: epel-all [bug 1475330] Affects: fedora-all [bug 1475328] Affects: openshift-1 [bug 1475329] Lowering severity to Medium to keep it aligned with similar remote DoS by hash table issues. The upstream fix pointed in the upstream release note (commit 51d69d2bec) was a temporary fix only, aimed at disabling snapshot by default, and had a negative performance impact during creation of contexts (e.g.: vm.runInNewContext() calls). A later patch re-enables snapshot by default, and adds re-hashing after de-serialization as mitigation : https://github.com/nodejs/node/commit/8dce05fa This issue has been addressed in the following products: Red Hat Software Collections for Red Hat Enterprise Linux 6 Red Hat Software Collections for Red Hat Enterprise Linux 6.7 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7 Red Hat Software Collections for Red Hat Enterprise Linux 7.3 EUS Via RHSA-2017:2908 https://access.redhat.com/errata/RHSA-2017:2908 This issue has been addressed in the following products: Red Hat Software Collections for Red Hat Enterprise Linux 6 Red Hat Software Collections for Red Hat Enterprise Linux 6.7 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7 Red Hat Software Collections for Red Hat Enterprise Linux 7.3 EUS Via RHSA-2017:3002 https://access.redhat.com/errata/RHSA-2017:3002 Openshift Enterprise uses latest RHSCL nodejs-4-rhel7 image which contains a fix for this issue. Marking Openshift Enterprise as not affected. https://github.com/openshift/library/blob/4e6ba65846f803063b1d977eaa57c89af440812f/official/nodejs/imagestreams/nodejs-rhel7.json#L64 Marking Openshift Online as not affected for the same reasons as comment 12. |
