Examining data/libapache2-mod-watchcat-1.1.2/mod_watchcat.c

FINAL RESULTS:

data/libapache2-mod-watchcat-1.1.2/mod_watchcat.c:358:16:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
        assert(strcat);

data/libapache2-mod-watchcat-1.1.2/mod_watchcat.c:208:15:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
    timeout = atoi(word2);

data/libapache2-mod-watchcat-1.1.2/mod_watchcat.c:254:12:  [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).
    assert(strlen(path) < CAT_DEVICE_SIZE);
