FINAL RESULTS:

data/py-radix-0.10.0/radix/_radix/radix.h:76:10:  [4] (format) snprintf:
  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.

data/py-radix-0.10.0/radix/_radix.c:67:9:  [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 network[256], prefix[256];
data/py-radix-0.10.0/radix/_radix/radix.c:136:17:  [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(&prefix->add.sin6, dest, 16);

        char addrbuf[128];
data/py-radix-0.10.0/radix/_radix/radix.c:802:21:  [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).
        if ((slen = strlen(string) + 1) > sizeof(save)) {
