Title: PHP EXIF extension缓冲区溢出漏洞（CNVD-2020-22810）

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。EXIF extension是其中的一个用于读取和编写图像元数据的扩展。

PHP 7.2.26之前的7.2.x版本、7.3.13之前的7.3.x版本和7.4.0版本中的EXIF extension存在缓冲区溢出漏洞。该漏洞源于网络系统或产品在内存上执行操作时，未正确验证数据边界，导致向关联的其他内存位置上执行了错误的读写操作。攻击者可利用该漏洞导致缓冲区溢出或堆溢出等。
