FINAL RESULTS:

data/globus-gfork-5.0/globus_gfork_server.c:192:5:  [4] (format) vfprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
    vfprintf(gfork_l_options.log_fptr, fmt, ap);
data/globus-gfork-5.0/globus_gfork_server.c:558:14:  [4] (shell) execv:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
        rc = execv(argv[0], argv);
data/globus-gfork-5.0/globus_gfork_server.c:1147:10:  [4] (shell) execv:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
    rc = execv(gfork_handle->server_argv[0], gfork_handle->server_argv);
data/globus-gfork-5.0/globus_gfork_lib.c:455:15:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
    tmp_str = getenv(env);
data/globus-gfork-5.0/globus_gfork_server.c:75:17:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
        env_s = getenv(gfork_l_keep_envs[i]);
data/globus-gfork-5.0/globus_gfork_server.c:554:13:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
            getenv(GFORK_CHILD_READ_ENV),

            getenv(GFORK_CHILD_WRITE_ENV));
data/globus-gfork-5.0/globus_gfork_opts.c:630:16:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
        fptr = fopen(opt[0], "w");
data/globus-gfork-5.0/globus_gfork_server.c:1229:17:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
                memcpy(msg2, msg, sizeof(gfork_i_msg_t));
data/globus-gfork-5.0/globus_gfork_server.c:1256:21:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
                    memcpy(msg2, msg, sizeof(gfork_i_msg_t));
data/globus-gfork-5.0/globus_gfork_server.c:1268:13:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
            memcpy(msg2, msg, sizeof(gfork_i_msg_t));
data/globus-gfork-5.0/globus_gfork_opts.c:127:33:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
        opts->crowded_msg_len = strlen(opts->crowded_msg);
data/globus-gfork-5.0/globus_gfork_opts.c:688:32:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
    gfork_h->crowded_msg_len = strlen(gfork_h->crowded_msg);
