Examining data/golang-github-erikdubbelboer-gspt-0.0~git20161002.0.6ce3e9d/setproctitle.h

FINAL RESULTS:

data/golang-github-erikdubbelboer-gspt-0.0~git20161002.0.6ce3e9d/setproctitle.h:214:11:  [4] (format) vsnprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
    len = vsnprintf(buf, sizeof buf, fmt, ap);
data/golang-github-erikdubbelboer-gspt-0.0~git20161002.0.6ce3e9d/setproctitle.h:204:3:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
  char buf[SPT_MAXTITLE + 1]; // Use buffer in case argv[0] is passed.
data/golang-github-erikdubbelboer-gspt-0.0~git20161002.0.6ce3e9d/setproctitle.h:232:3:  [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(SPT.base, buf, len);
data/golang-github-erikdubbelboer-gspt-0.0~git20161002.0.6ce3e9d/setproctitle.h:124:12:  [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).
    ptr -= strlen(arg0);
data/golang-github-erikdubbelboer-gspt-0.0~git20161002.0.6ce3e9d/setproctitle.h:156:15:  [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).
  nul = &base[strlen(base)];
data/golang-github-erikdubbelboer-gspt-0.0~git20161002.0.6ce3e9d/setproctitle.h:163:21:  [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).
    end = argv[i] + strlen(argv[i]) + 1;
data/golang-github-erikdubbelboer-gspt-0.0~git20161002.0.6ce3e9d/setproctitle.h:170:21:  [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).
    end = envp[i] + strlen(envp[i]) + 1;
