FINAL RESULTS:
data/libb-hooks-op-annotation-perl-0.44/ppport.h:6695:14: [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-op-annotation-perl-0.44/ppport.h:6697:14: [4] (format) vsprintf:
Potential format string problem (CWE-134). Make format string constant.
retval = vsprintf(buffer, format, ap);
data/libb-hooks-op-annotation-perl-0.44/ppport.h:6726:5: [4] (format) vsprintf:
Potential format string problem (CWE-134). Make format string constant.

data/libb-hooks-op-annotation-perl-0.44/ppport.h:3667:42: [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-op-annotation-perl-0.44/ppport.h:6550:24: [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-op-annotation-perl-0.44/ppport.h:6772:9: [2] (buffer) memcpy:

data/libb-hooks-op-annotation-perl-0.44/ppport.h:6801:9: [2] (buffer) memcpy:

data/libb-hooks-op-annotation-perl-0.44/ppport.h:6893:5: [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.

functions that limit length, or ensure that the size is larger than the
