FINAL RESULTS:
data/libb-hooks-parser-perl-0.21/ppport.h:7585:14: [4] (format) vsnprintf:
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.
retval = vsnprintf(buffer, len, format, ap);
data/libb-hooks-parser-perl-0.21/ppport.h:7587:14: [4] (format) vsprintf:
Potential format string problem (CWE-134). Make format string constant.
retval = vsprintf(buffer, format, ap);
data/libb-hooks-parser-perl-0.21/ppport.h:7617:5: [4] (format) vsprintf:
Potential format string problem (CWE-134). Make format string constant.
vsprintf(buffer, pat, args);
data/libb-hooks-parser-perl-0.21/ppport.h:3920:42: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
# define CopyD(s,d,n,t) memcpy((char*)(d),(char*)(s), (n) * sizeof(t))
data/libb-hooks-parser-perl-0.21/ppport.h:7438:38: [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.
&& (xdigit = strchr((char *) PL_hexdigit, s[1])))
data/libb-hooks-parser-perl-0.21/ppport.h:7664:9: [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(dst + used, src, copy);
data/libb-hooks-parser-perl-0.21/ppport.h:7694:9: [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(dst, src, copy);
data/libb-hooks-parser-perl-0.21/ppport.h:7787:5: [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 octbuf[32] = "%123456789ABCDF";
data/libb-hooks-parser-perl-0.21/ppport.h:7857:13: [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 tmp[2];
data/libb-hooks-parser-perl-0.21/stolen_chunk_of_toke.c:433:6: [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 smallbuf[256], smallbuf2[256];
data/libb-hooks-parser-perl-0.21/stolen_chunk_of_toke.c:448:6: [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(tmpbuf + 2, cf, ++tmplen);
data/libb-hooks-parser-perl-0.21/stolen_chunk_of_toke.c:449:6: [2] (buffer) memcpy:

memcpy(tmpbuf2 + 2, s, ++tmplen2);
data/libb-hooks-parser-perl-0.21/stolen_chunk_of_toke.c:471:28: [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).
