Upgrade Ubuntu:18.04 php7.2 to version 7.2.3-1ubuntu1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php7.2 package and not the php7.2 package as distributed by Ubuntu.
See How to fix? for Ubuntu:18.04 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.
