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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
