CVE-2017-14064 (opens in a new tab)How to fix?
Upgrade Debian:9 ruby2.3 to version 2.3.3-1+deb9u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby2.3 package and not the ruby2.3 package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
Ruby through 2.2.7, 2.3.x through 2.3.4, and 2.4.x through 2.4.1 can expose arbitrary memory during a JSON.generate call. The issues lies in using strdup in ext/json/ext/generator/generator.c, which will stop after encountering a '\0' byte, returning a pointer to a string of length zero, which is not the length stored in space_len.
