Title

Oniguruma 'match_at()'函数缓冲区溢出漏洞

Description

mbstring（Multi-Byte String）是PHP（PHP：Hypertext Preprocessor，PHP：超文本预处理器）中的一个语言编码扩展库；Oniguruma-mod是Ruby（编程语言）中的一个正则表达式库。Oniguruma是其中的一个正则表达式引擎。 Ruby 2.4.1及之前的版本的Oniguruma-mod和PHP 7.1.5及之前的版本的mbstring中使用的Oniguruma 6.2.0版本的'match_at()'函数存在缓冲区溢出漏洞。攻击者可利用该漏洞造成拒绝服务（栈越边界读取）。
