Examining data/yc-el-5.0.0/icanna.c

FINAL RESULTS:

data/yc-el-5.0.0/icanna.c:39:3:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
  strcpy(sun.sun_path, CANNA_PATH);
data/yc-el-5.0.0/icanna.c:69:16:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    if ((len = read(in, buf + count * BFSZ, BFSZ)) < 0) {
