Description Andrej Nemec 2017-11-22 08:30:59 UTC

Node.js before 4.8.5, 6.x before 6.11.5, and 8.x before 8.8.0 allows remote attackers to cause a denial of service (uncaught exception and crash) by leveraging a change in the zlib module 1.2.9 making 8 an invalid value for the windowBits parameter.

rh-nodejs6-nodejs and rh-nodejs8-nodejs contain the fixed code already. rh-nodejs4-nodejs does not, but we don't ship zlib 1.2.9, so it does not really matter for RHSCL/RHEL.

Comment 5 Jason Shepherd 2018-04-03 05:15:59 UTC

Openshift Enterprise uses the RHSCL nodejs-4-rhel7 image which doesn't include zlib 1.2.9. Marking as not affected.
