Examining data/preprepare-0.9/pre_prepare.c

FINAL RESULTS:

data/preprepare-0.9/pre_prepare.c:72:3:  [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.
  snprintf(select, len, stmpl, relation_name);

  If format strings can be influenced by an attacker, they can be exploited,

  a constant for the format specification.
  snprintf(select, len, stmpl, relation_name);
data/preprepare-0.9/pre_prepare.c:69:19:  [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).
  int len      = (strlen(stmpl) - 2) + strlen(relation_name) + 1;

  int len      = (strlen(stmpl) - 2) + strlen(relation_name) + 1;
