    Can gethostbyname be exploited?

    Hey,

    I wondered about the function:

    gethostbyname(argv[2]);

    can this be exploited by an Bufferoverflow attack?

    Thank you!

    If we exclude possible implementation-specific bugs, no.

    OBS: gethostbyname() and gethostbyaddr() are deprecated since 2008 (POSIX-1:2008). Use getaddrinfo() and getnameinfo().
