Title: Oniguruma 'onigenc_unicode_get_case_fold_codes_by_str()'函数栈缓冲区溢出漏洞

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'onigenc_unicode_get_case_fold_codes_by_str()'函数存在栈缓冲区溢出漏洞。攻击者可利用该漏洞造成拒绝服务（栈越边界写入）。

Severity: 高

Vulnerability from cvelistv5

Published

Severity ?

CWE

Summary

An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds write in onigenc_unicode_get_case_fold_codes_by_str() occurs during regular expression compilation. Code point 0xFFFFFFFF is not properly handled in unicode_unfold_key(). A malformed regular expression could result in 4 bytes being written off the end of a stack buffer of expand_case_fold_string() during the call to onigenc_unicode_get_case_fold_codes_by_str(), a typical stack buffer overflow.
