漏洞描述
中文描述:
Google API C++ Client是美国谷歌（Google）的一款基于C++的Google API客户端库。 Google API C++ Client 2019-04-10之前版本中存在安全漏洞。攻击者可利用该漏洞造成拒绝服务。
英文描述:
An unhandled exception vulnerability exists during Google Sign-In with Google API C++ Client before 2019-04-10. It potentially causes an outage of third-party services that were not designed to recover from exceptions. On the client, ID token handling can cause an unhandled exception because of misinterpretation of an integer as a string, resulting in denial-of-service and then other users can no longer login/sign-in to the affected third-party service. Once this third-party service uses Google Sign-In with google-api-cpp-client, a malicious user can trigger this client/auth/oauth2_authorization.cc vulnerability by requesting the client to receive the ID token from a Google authentication server.
