**Name of the Vulnerable Software and Affected Versions**
PHP versions 7.0.x through 7.0.26
PHP versions 7.1.x through 7.1.12
PHP versions 7.2.x through 7.2.0
**Description**
The issue arises from inappropriately parsing an HTTP response, leading to a segmentation fault. This occurs because the `http header value` in ext/standard/http fopen wrapper.c can be a NULL value that is mishandled in an atoi call. The vulnerability is related to the `http header value` function and can be exploited by a remote attacker to cause a denial of service.

For PHP versions 7.1.x through 7.1.12, update to version 7.1.13 or later.
For PHP versions 7.2.x through 7.2.0, update to version 7.2.1 or later.
