FINAL RESULTS:
data/libsort-key-perl-1.33/ppport.h:5729:14: [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/libsort-key-perl-1.33/ppport.h:5731:14: [4] (format) vsprintf:
Potential format string problem (CWE-134). Make format string constant.
retval = vsprintf(buffer, format, ap);
data/libsort-key-perl-1.33/ppport.h:3371:42: [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/libsort-key-perl-1.33/ppport.h:5584:24: [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.

data/libsort-key-perl-1.33/ppport.h:5780:9: [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/libsort-key-perl-1.33/ppport.h:5809:9: [2] (buffer) memcpy:
