FINAL RESULTS:
data/libxtrxdsp-0.0.1+git20190830.eec2864/xtrxdsp.c:42:24: [4] (format) fprintf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
#define INFORM(x, ...) fprintf(stderr, x, ##__VA_ARGS__)
data/libxtrxdsp-0.0.1+git20190830.eec2864/tests/test_filter.c:42:16: [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 ((opt = getopt(argc, argv, "m:i:o:d:I:b:F:f:")) != -1) {
data/libxtrxdsp-0.0.1+git20190830.eec2864/xtrxll_port.h:72:2: [3] (misc) InitializeCriticalSection:
Exceptions can be thrown in low-memory situations. Use
InitializeCriticalSectionAndSpinCount instead.
InitializeCriticalSection(__mutex);
data/libxtrxdsp-0.0.1+git20190830.eec2864/xtrxll_port.h:82:2: [3] (misc) EnterCriticalSection:
On some versions of Windows, exceptions can be thrown in low-memory
situations. Use InitializeCriticalSectionAndSpinCount instead.

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).

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).

data/libxtrxdsp-0.0.1+git20190830.eec2864/xtrxll_port.h:127:5: [1] (obsolete) usleep:
This C routine is considered obsolete (as opposed to the shell command by
the same name). The interaction of this function with SIGALRM and other
timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
