FINAL RESULTS:

data/trend-1.4/src/trend.cc:1968:16:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
  while((arg = getopt(argc, argv, "dDSsvlmFgG:ht:A:E:R:I:M:N:T:L:irz:f:c:p:u:e")) != -1)
data/trend-1.4/src/trend.cc:50:12:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
using std::memcpy;
data/trend-1.4/src/trend.cc:290:5:  [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[Trend::maxNumLen];
data/trend-1.4/src/trend.cc:388:22:  [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).
    in = (*fileName? fopen(fileName, "r"): stdin);
data/trend-1.4/src/trend.cc:1139:3:  [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[256];
data/trend-1.4/src/trend.cc:1173:3:  [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[256];
data/trend-1.4/src/trend.cc:1183:3:  [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[256];
data/trend-1.4/src/trend.cc:1207:3:  [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[256];
data/trend-1.4/src/trend.cc:1275:3:  [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[256];
data/trend-1.4/src/trend.cc:2187:3:  [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[Trend::maxNumLen];
data/trend-1.4/src/trend.cc:2215:7:  [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(gi->lineCol, Trend::lineCol[n % maxLineCol], sizeof(GLfloat[3]));
data/trend-1.4/src/trend.cc:51:12:  [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).
using std::strlen;
