ruby: BasicSocket#read_nonblock method leads to information disclosure

An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocketreadnonblockrequestedsize, 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 valu...

An issue was discovered in Ruby 2.5.x through 2.5.7 2.6.x through 2.6.5 and 2.7.0. 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.
