Vulnerability from cnvd

Title: International Components for Unicode/C++拒绝服务漏洞

Description:

International Components for Unicode（ICU）是一个为C/C++和Java编程语言提供了一整套操作Unicode数据的函数库，也是一个用于支持软件国际化的开源项目。

International Components for Unicode的common/uloc.cpp文件中的‘uloc_acceptLanguageFromHTTP’函数没有确认临时数组以‘\0’字符结尾，允许远程攻击者可利用漏洞提交较长的httpAcceptLanguage参数调用函数进行拒绝服务攻击。

Severity: 高

Summary

The uloc_acceptLanguageFromHTTP function in common/uloc.cpp in International Components for Unicode (ICU) through 57.1 for C/C++ does not ensure that there is a '\0' character at the end of a certain temporary array, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a call with a long httpAcceptLanguage argument.
