pcnet: fix possible buffer overflow
In pcnet_receive(), we try to assign size_ to size which converts from size_t to integer. This will cause troubles when size_ is greater INT_MAX, this will lead a negative value in size and it can then pass the check of size < MIN_BUF_SIZE which may lead out of bound access for both buf and buf1. Fixing by converting the type of size to size_t. CC: qemu-stable@nongnu.org Reported-by: Daniel Shapira <daniel@twistlock.com> Reviewed-by: Michael S.
