FINAL RESULTS:
data/forge-1.0.1/src/backend/defines.hpp:32:17: [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.
#define snprintf sprintf_s
data/forge-1.0.1/src/backend/opengl/common.cpp:279:5: [4] (format) sprintf:
Potential format string problem (CWE-134). Make format string constant.
sprintf(label.get(), pFormat.c_str(), pVal);
data/forge-1.0.1/examples/cpu/histogram.cpp:142:10: [3] (random) srand:
This function is not sufficiently random for security-related functions
such as key and nonce creation (CWE-327). Use a more secure technique for
acquiring random values.
std::srand(std::time(0));
data/forge-1.0.1/examples/opencl/bubblechart.cpp:95:10: [3] (random) srand:
This function is not sufficiently random for security-related functions
such as key and nonce creation (CWE-327). Use a more secure technique for
acquiring random values.
std::srand(std::time(0));
data/forge-1.0.1/examples/opencl/histogram.cpp:168:10: [3] (random) srand:
This function is not sufficiently random for security-related functions
such as key and nonce creation (CWE-327). Use a more secure technique for
acquiring random values.
std::srand(std::time(0));
data/forge-1.0.1/src/backend/util.cpp:34:18: [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.
char * str = getenv(key.c_str());
data/forge-1.0.1/include/fg/exception.h:25:5: [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 mMessage[1024];
data/forge-1.0.1/src/backend/opengl/common.cpp:227:4: [2] (buffer) TCHAR:
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.
TCHAR szDir[MAX_PATH];
data/forge-1.0.1/src/backend/opengl/font_atlas_impl.cpp:238:18: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
std::memcpy(mData.data() + ((pY+i)*mWidth + pX) * charsize * depth,
data/forge-1.0.1/src/backend/opengl/font_impl.cpp:377:5: [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[512];
data/forge-1.0.1/src/api/cpp/exception.cpp:27:5: [1] (buffer) strncpy:
Easily used incorrectly; doesn't always \0-terminate or check for invalid
pointers [MS-banned] (CWE-120).
strncpy(dest, src, len);
data/forge-1.0.1/src/backend/opengl/font_impl.cpp:444:29: [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).
for (size_t i=0; i<std::strlen(pText); ++i)
