FINAL RESULTS:

data/libclass-xsaccessor-perl-1.19/ppport.h:6890:14:  [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/libclass-xsaccessor-perl-1.19/ppport.h:6892:14:  [4] (format) vsprintf:
  Potential format string problem (CWE-134). Make format string constant.
    retval = vsprintf(buffer, format, ap);
data/libclass-xsaccessor-perl-1.19/ppport.h:6921:5:  [4] (format) vsprintf:
  Potential format string problem (CWE-134). Make format string constant.
    vsprintf(buffer, pat, args);
data/libclass-xsaccessor-perl-1.19/cxsa_memory.c:21:12:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
    return memcpy(dest, src, size);
data/libclass-xsaccessor-perl-1.19/ppport.h:3842:42:  [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/libclass-xsaccessor-perl-1.19/ppport.h:6745:24:  [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/libclass-xsaccessor-perl-1.19/ppport.h:6967:9:  [2] (buffer) memcpy:

        memcpy(dst + used, src, copy);
data/libclass-xsaccessor-perl-1.19/ppport.h:6996:9:  [2] (buffer) memcpy:

data/libclass-xsaccessor-perl-1.19/ppport.h:7088:5:  [2] (buffer) char:

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