FINAL RESULTS:
data/c2hs-0.28.6/tests/bugs/issue-60/stdlib.h:365:37: [4] (shell) system:
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.
_CRTIMP int __cdecl __MINGW_NOTHROW system (const char*);
data/c2hs-0.28.6/tests/bugs/issue-60/stdlib.h:353:38: [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.
_CRTIMP void __cdecl __MINGW_NOTHROW srand (unsigned int);
data/c2hs-0.28.6/tests/bugs/issue-60/stdlib.h:366:39: [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.
_CRTIMP char* __cdecl __MINGW_NOTHROW getenv (const char*);
data/c2hs-0.28.6/tests/bugs/issue-22/issue22.c:9:3: [2] (buffer) strcpy:
Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused). Risk is low because the source is a constant string.
strcpy(s.somefield, "abcdef");
data/c2hs-0.28.6/tests/bugs/issue-22/issue22.h:6:5: [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 somefield[32];
data/c2hs-0.28.6/tests/bugs/issue-60/stdlib.h:304:37: [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).
_CRTIMP int __cdecl __MINGW_NOTHROW atoi (const char*);
data/c2hs-0.28.6/tests/bugs/issue-60/stdlib.h:305:39: [2] (integer) atol:
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).

data/c2hs-0.28.6/tests/bugs/issue-60/stdlib.h:308:37: [2] (integer) _wtoi:
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).

data/c2hs-0.28.6/tests/bugs/issue-60/stdlib.h:431:41: [2] (integer) _wtoi64:
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).
