Headers missing a colon (":") are treated as valid, even though they are not, confusing applications into accepting invalid headers.

Recommendations

If you are using the PHP streams HTTP wrapper to make HTTP requests, we recommend using another HTTP request extension, such as cURL, if you are unable to update.

Otherwise, we recommend upgrading to a known patched version of PHP.
