Title: PHP输入验证错误漏洞（CNVD-2020-33148）

Description:

PHP（PHP：Hypertext Preprocessor，PHP：超文本预处理器）是PHPGroup和开放源代码社区的共同维护的一种开源的通用计算机脚本语言。该语言主要用于Web开发，支持多种数据库及操作系统。

PHP 7.2.31之前的7.2.x版本、7.3.18之前的7.3.x版本和7.4.6之前的7.4.x版本中存在输入验证错误漏洞，该漏洞源于在通过HTTP协议上传文件时，如果文件名或字段名过长，PHP引擎会分配过大内存，达到内存限制并停止处理请求，但不会清除创建的临时文件。攻击者可利用该漏洞导致拒绝服务。
