4 | Subject: [PATCH] pcnet: fix possible buffer overflow | ||
5 | |||
6 | In pcnet_receive(), we try to assign size_ to size which converts from | ||
7 | size_t to integer. This will cause troubles when size_ is greater | ||
8 | INT_MAX, this will lead a negative value in size and it can then pass | ||
9 | the check of size < MIN_BUF_SIZE which may lead out of bound access | ||
10 | for both buf and buf1. | ||
11 | |||
12 | Fixing by converting the type of size to size_t. | ||
