Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
