FINAL RESULTS:
data/libsharp-1.0.0/libsharp/sharp_testsuite.c:649:7: [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.
getenv("HOST"),argv[2],spin,sharp_veclen(),nomp,ntasks,lmax,mmax,gpar1,gpar2,
data/libsharp-1.0.0/c_utils/memusage.c:34:17: [2] (misc) fopen:
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).
FILE *statm = fopen("/proc/self/statm","r");
data/libsharp-1.0.0/c_utils/memusage.c:45:3: [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 word[1024];
data/libsharp-1.0.0/c_utils/memusage.c:46:13: [2] (misc) fopen:
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).
FILE *f = fopen("/proc/self/status", "r");
data/libsharp-1.0.0/libsharp/sharp.c:670:11: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy(p1,p2,ri->nph*sizeof(double));
data/libsharp-1.0.0/libsharp/sharp.c:695:9: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy(p1,p2,ri->nph*sizeof(double));
data/libsharp-1.0.0/libsharp/sharp_testsuite.c:573:12: [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 lmax=atoi(argv[3]);
data/libsharp-1.0.0/libsharp/sharp_testsuite.c:574:12: [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 mmax=atoi(argv[4]);
data/libsharp-1.0.0/libsharp/sharp_testsuite.c:575:13: [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 gpar1=atoi(argv[5]);
data/libsharp-1.0.0/libsharp/sharp_testsuite.c:576:13: [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 gpar2=atoi(argv[6]);
data/libsharp-1.0.0/libsharp/sharp_testsuite.c:577:12: [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 spin=atoi(argv[7]);
data/libsharp-1.0.0/pocketfft/pocketfft.c:918:7: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy (c,p1,len*sizeof(cmplx));
data/libsharp-1.0.0/pocketfft/pocketfft.c:1692:7: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy (c,p1,n*sizeof(double));
data/libsharp-1.0.0/pocketfft/pocketfft.c:2026:3: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy (tmp+2,c+1, (n-1)*sizeof(double));
data/libsharp-1.0.0/pocketfft/pocketfft.c:2055:3: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy (c+1, tmp+2, (n-1)*sizeof(double));
data/libsharp-1.0.0/c_utils/memusage.c:51:9: [1] (buffer) fscanf:
It's unclear if the %s limit in the format string is small enough
(CWE-120). Check that the limit is sufficiently small, or use a different
input function.
if (fscanf (f,"%1023s",word)<0)
data/libsharp-1.0.0/c_utils/memusage.c:55:11: [1] (buffer) fscanf:
It's unclear if the %s limit in the format string is small enough
(CWE-120). Check that the limit is sufficiently small, or use a different
input function.
if (fscanf(f,"%lf%2s",&res,word)<0)
data/libsharp-1.0.0/libsharp/sharp_testsuite.c:72:18: [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).
size_t m, nlen=strlen(name);
