This issue is a very limited information leak / out of bounds read, caused by a failure to nul terminate string in certain cases. The use of term "leak" is misleading, as it's not a resource leak / failure to de-allocate memory after its effective life time. Practically, only few bytes or memory are disclosed, unlikely to disclose sensitive information. This issue is in the intl (Internationalization) extension. In Red Hat products, this extension is packaged separately in php-intl sub-RPM. Systems without that package installed can not be affected by this issue.
