Segmentation Fault due to PHP bug in preg_match

EUriHttp

    public function validateQuery($query = null)
    {
        if ($query === null)
        {
            $query = $this->_query;
        }

        // If query is empty, it is considered to be valid
        if (strlen($query) === 0)
        {
            return true;
        }

        // Determine whether the query is well-formed
        $pattern = '/^' . $this->_regex['uric'] . '*$/';
        $status = @preg_match($pattern, $query);
        if ($status === false)
        {
            throw new CException('Internal error: query validation failed');
        }

        return $status == 1;
    }

preg_match in this function can crash PHP execution if URI is too long.

Possible solution: ZF-10151: Improved notification in Http.php validateQuery() over preg_match crash caused by PHP backtracking bug

Probably same issue can appear: EUriHttp

    public function validateFragment($fragment = null)
    {
        if ($fragment === null)
        {
            $fragment = $this->_fragment;
        }

        // If fragment is empty, it is considered to be valid
        if (strlen($fragment) === 0)
        {
            return true;
        }

        // Determine whether the fragment is well-formed
        $pattern = '/^' . $this->_regex['uric'] . '*$/';
        $status = @preg_match($pattern, $fragment);
        if ($status === false)
        {
            throw new CException('Internal error: fragment validation failed');
        }

        return (boolean) $status;
    }
