An issue was discovered in Ruby through 2.5.7. If a victim calls
BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method
resizes the buffer to fit the requested size, but no data is copied. Thus, the
buffer string provides the previous value of the heap. This may expose possibly
sensitive data from the interpreter (CVE-2020-10933).");
