This adds a check to the C function
jl_callocto prevent overflow. The specific change here was previously reviewed by @vtjnash in #42704 and includes a revision by him to useSSIZE_MAXrather thanSIZE_MAX. I've extracted the relevant code from the large set of changes.This makes
jl_callocSCI CERT MEM07-C compliant such that it avoids issues as inRUS-CERT Advisory 2002-08:02orCVE-2002-039.Fixes #42673
