    Problem Report Number 1293
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0575
    Raised 1970-01-01 08:00
    Updated 2003-03-13 08:00
    Published 1998-07-14 08:00
    Product Standard Internationalised Terminal Interfaces
    Certification Program The Open Brand certification program
    Test Suite VSU version 5.0.2
    Test Identification header/xcurses 579
    Problem Summary TSD4U.00243 This test may fail on implementations which provide a macro version of mvwinstr.
    Problem Text
    Here is the failing portion of the test code:

    static void test579A(void)
    {
    ...
    wchar_t *wstr;
    wchar_t wdata[2] = {(wchar_t)'a', 0};
    ...
    wstr = wdata;
    ...
    (void) mvwinwstr(ret1 = (arg1++, win), ret2 = (arg2++, y),
    ret3 = (arg3++, x), ret4 = (arg4++, wstr));
    ...
    }

    mvwinstr() here loads wstr with an uninitialized value from the screen. If that
    value doesn't fit in two characters, the buffer overflows and the result is
    undefined.

    The test should allot a larger buffer.
