NVD Description

Note: Versions mentioned in the description apply only to the upstream php7.0 package and not the php7.0 package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

In PHP through 5.6.33, 7.0.x before 7.0.28, 7.1.x through 7.1.14, and 7.2.x through 7.2.2, there is a stack-based buffer under-read while parsing an HTTP response in the php_stream_url_wrap_http_ex function in ext/standard/http_fopen_wrapper.c. This subsequently results in copying a large string.
