Check sh_entsize is not zero. There were some recent bug reports where we trusted the ELF section header to be sane and divided the sh_size by the sh_entsize to get the number of objects in the section. This would cause a divide by zero if the file was corrupt and the sh_entsize was zero. Add checks for any such code. Signed-off-by: Mark Wielaard <mark@klomp.org>
