NVD Description

Note: Versions mentioned in the description apply only to the upstream php7 package and not the php7 package as distributed by Alpine. See How to fix? for Alpine:3.7 relevant fixed versions and status.

An issue was discovered in PHP 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before 7.2.1. Inappropriately parsing an HTTP response leads to a segmentation fault because http_header_value in ext/standard/http_fopen_wrapper.c can be a NULL value that is mishandled in an atoi call.
