NVD Description
Note: Versions mentioned in the description apply only to the upstream hhvm package and not the hhvm package as distributed by Ubuntu.
folly::secureRandom will re-use a buffer between parent and child processes when fork() is called. That will result in multiple forked children producing repeat (or similar) results. This affects HHVM 3.26 prior to 3.26.3 and the folly library between v2017.12.11.00 and v2018.08.09.00.
