Laurent Goujon created DRILL-5668: ------------------------------------- Summary: C++ connector crash when query error message is too long Key: DRILL-5668 URL: https://issues.apache.org/jira/browse/DRILL-5668 Project: Apache Drill Issue Type: Bug Components: Client - C++ Affects Versions: 1.10.0 Reporter: Laurent Goujon Assignee: Laurent Goujon Fix For: 1.11.0
The C++ connector crashes if the query sent to the server is invalid and the error message returned by the server is too long. The cause of the crash is a call to a {{vsprintf}} function which takes a fixed sized char buffer, but doesn't take a size argument. https://github.com/apache/drill/blob/master/contrib/native/client/src/clientlib/errmsgs.cpp#L80 -- This message was sent by Atlassian JIRA (v6.4.14#64029)
