Examining data/mod-vhost-ldap-2.4.0/mod_vhost_ldap.c

FINAL RESULTS:

data/mod-vhost-ldap-2.4.0/mod_vhost_ldap.c:283:9:  [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(p, urld->lud_host);
data/mod-vhost-ldap-2.4.0/mod_vhost_ldap.c:285:9:  [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).
        strcat(p, conf->host);
data/mod-vhost-ldap-2.4.0/mod_vhost_ldap.c:459:5:  [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 filtbuf[FILTER_LENGTH];
data/mod-vhost-ldap-2.4.0/mod_vhost_ldap.c:282:41:  [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).
        char *p = apr_palloc(cmd->pool, strlen(conf->host) + strlen(urld->lud_host) + 2);
data/mod-vhost-ldap-2.4.0/mod_vhost_ldap.c:282:62:  [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).
        char *p = apr_palloc(cmd->pool, strlen(conf->host) + strlen(urld->lud_host) + 2);
data/mod-vhost-ldap-2.4.0/mod_vhost_ldap.c:284:9:  [1] (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). Risk is low because the
  source is a constant character.
        strcat(p, " ");
data/mod-vhost-ldap-2.4.0/mod_vhost_ldap.c:303:26:  [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).
            conf->filter[strlen(conf->filter)-1] = '\0';
data/mod-vhost-ldap-2.4.0/mod_vhost_ldap.c:638:57:  [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).
        cgi = apr_pstrcat(r->pool, reqc->cgiroot, cgi + strlen("cgi-bin"), NULL);
