net-ftp/atftp-0.7 segfaults everytime a command is entered, regardless of whether the command is valid or not. Any input at all results in a segfault. This only occurs with commands entered on aftp's own little config thing. If every needed option is specified as command line arguments, then it works perfectly. Below is an example of the segfaulting: $ atftp tftp> host 192.168.2.1 Segmentation fault $ atftp tftp> mode binary Segmentation fault $ atftp tftp> argh! Segmentation fault Reproducible: Always Steps to Reproduce: 1. emerge atftp 2. execute 'atftp' 3. attempt to enter a command Actual Results: Segfault. Expected Results: It should have accepted the command and allowed you to specify further commands before sending the file.

I just emerged this packages and saw this bug as well. I couldn't download atftp from the vendors website, so I just took a look in the source code from portage. The problem is in tftp.c in the make_arg function (line 357 for me); the argz_len variable is defined as "int" where it should be "size_t". This problem may not be showing on i386 machines because perhaps "int" and "size_t" are the same on that platform? not sure, but I'm running amd64 and since the argz_create_sep function thinks it's taking a pointer to "size_t", it fills up the whole size of that variable when it sets it, therefore on my system, when it passes an int, it is overwriting 4 bytes on the stack as all zeros which just happens to be the argv pointer in make_arg which is causing a segfault. Anyways, just change the "int" to "size_t" like it should be (gcc warnings warn you of this anyways) and it will fix the problem.
Created attachment 75407 [details, diff] Patch to fix the above mentioned problem.
fixed in cvs (via the debian patch).
