FINAL RESULTS:

data/apache-upload-progress-module-0.2/mod_upload_progress.c:206:17:  [4] (buffer) sscanf:
  The scanf() family's %s operation, without a limit specification, permits
  buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
  different input function. If the scanf format is influenceable by an
  attacker, it's exploitable.
                sscanf(content_length, "%" APR_OFF_T_FMT, &(node->length));
data/apache-upload-progress-module-0.2/mod_upload_progress.c:83:9:  [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 errbuf[200];                                  \
data/apache-upload-progress-module-0.2/mod_upload_progress.c:114:5:  [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 key[ARG_MAXLEN_PROGRESSID];
data/apache-upload-progress-module-0.2/mod_upload_progress.c:253:23:  [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).
    long long int n = atoi(arg);
data/apache-upload-progress-module-0.2/mod_upload_progress.c:309:35:  [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).
        status = r->status_line ? atoi(r->status_line) : 0;
data/apache-upload-progress-module-0.2/mod_upload_progress.c:372:5:  [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/apache-upload-progress-module-0.2/mod_upload_progress.c:485:13:  [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(node, new_data, sizeof(upload_progress_node_t));

  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
            memcpy(node, new_data, sizeof(upload_progress_node_t));
data/apache-upload-progress-module-0.2/mod_upload_progress.c:193:13:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
            strncpy(node->key, id, ARG_MAXLEN_PROGRESSID);
data/apache-upload-progress-module-0.2/mod_upload_progress.c:373:18:  [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 pn_len = strlen(param_name);
data/apache-upload-progress-module-0.2/mod_upload_progress.c:396:51:  [1] (buffer) strlen:
