FINAL RESULTS:

data/qsampler-0.6.3/src/qsampler.cpp:439:2:  [4] (format) snprintf:
  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.
	snprintf(cmd, sizeof(cmd), format, (int) getpid());
data/qsampler-0.6.3/src/qsampler.cpp:449:3:  [4] (shell) execl:
  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.
		execl(shell, shell, "-c", cmd, nullptr);
data/qsampler-0.6.3/src/qsampler.cpp:501:16:  [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.
		QString path(getenv("PATH"));
data/qsampler-0.6.3/src/qsampler.cpp:226:3:  [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 szHostName[255];
data/qsampler-0.6.3/src/qsampler.cpp:430:2:  [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 cmd[80];
data/qsampler-0.6.3/src/qsamplerChannel.cpp:670:25:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
		m_audioRouting[i] = ::atoi(ppszAudioRouting[i]);
data/qsampler-0.6.3/src/qsamplerChannel.cpp:815:11:  [2] (misc) open:
  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).
