What's the reason for using malloc(3) in the first place?  Is this a limitation
of the library or just  openssl cms ?

For the latter, if the argument to  -in  can be determined to resolve to a file
descriptor of a regular file, the file's contents can be /very/ conveniently mmap(2)'ed
into the process' address space, ignoring possible limits.


Thanks,
Christian
