Description Pedro Sampaio 2018-02-27 14:36:51 UTC 
The SQLWriteFileDSN function in odbcinst/SQLWriteFileDSN.c in unixODBC 2.3.5 has strncpy arguments in the wrong order, which allows attackers to cause a denial of service or possibly have unspecified other impact.

Comment 3 Huzaifa S. Sidhpurwala 2018-12-11 03:56:31 UTC 
Analysis:

This flaw is essentially an argument order confusion in the SQLWriteFileDSN API, can only be exploited via a malicious ODBC database connector package and can possible cause Denial of Service only. We believe that arbitrary code execution is not possible, therefore this flaw has been rated as having Moderate security impact.
