原文摘录

摘自原文(3760 字符中的一小部分)
First off, I know torsocks isn't in scope, so I don't expect anything in return for this. I happened to stumble upon this so why not report it. However if you feel generous you're welcome to give me bounty/swag ofcourse :P.
原文中的代码
 62 LIBC_GETHOSTBYNAME_RET_TYPE tsocks_gethostbyname(LIBC_GETHOSTBYNAME_SIG)
 63 {
 64     int ret;
 65     uint32_t ip;
 ...
 86     memcpy(tsocks_he_addr, &ip, sizeof(tsocks_he_addr));
