FINAL RESULTS:
data/r-cran-reticulate-1.18+dfsg/src/libpython.cpp:60:21: [3] (misc) LoadLibraryEx:
Ensure that the full path to the library is specified, or current directory
may be used (CWE-829, CWE-20). Use registry entry or GetWindowsDirectory to
find library path, if you aren't already.
*ppLib = (void*)::LoadLibraryEx(libPath.c_str(), NULL, 0);
data/r-cran-reticulate-1.18+dfsg/src/tinythread.h:171:7: [3] (misc) InitializeCriticalSection:
Exceptions can be thrown in low-memory situations. Use
InitializeCriticalSectionAndSpinCount instead.
InitializeCriticalSection(&mHandle);
data/r-cran-reticulate-1.18+dfsg/src/tinythread.h:194:7: [3] (misc) EnterCriticalSection:
On some versions of Windows, exceptions can be thrown in low-memory
situations. Use InitializeCriticalSectionAndSpinCount instead.
EnterCriticalSection(&mHandle);

situations. Use InitializeCriticalSectionAndSpinCount instead.
EnterCriticalSection(&mWaitersCountLock);
data/r-cran-reticulate-1.18+dfsg/src/tinythread.h:756:3: [3] (misc) InitializeCriticalSection:

data/r-cran-reticulate-1.18+dfsg/src/tinythread.h:793:3: [3] (misc) EnterCriticalSection:

data/r-cran-reticulate-1.18+dfsg/src/python.cpp:1676:11: [2] (buffer) wchar_t:
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.
const wchar_t *argv[1] = {s_python_v3.c_str()};
data/r-cran-reticulate-1.18+dfsg/src/python.cpp:1698:11: [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.
const char *argv[1] = {s_python.c_str()};
data/r-cran-reticulate-1.18+dfsg/src/python.cpp:1718:19: [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).
int tracems = ::atoi(tracems_env.c_str());
data/r-cran-reticulate-1.18+dfsg/src/readline.cpp:11:3: [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 buffer[READLINE_BUFFER_SIZE];
data/r-cran-reticulate-1.18+dfsg/src/readline.cpp:16:39: [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).
std::string result(buffer, buffer + strlen(buffer));
data/r-cran-reticulate-1.18+dfsg/src/tinythread.h:706:5: [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.
usleep(int(double(aTime.count()) * (1000000.0 * _Period::_as_double()) + 0.5));
