    Problem Report Number 1681
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Rejected (REJ)
    Problem Resolution ID REJ.X.0485
    Raised 2003-02-14 08:00
    Updated 2003-03-13 08:00
    Published null
    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSU version 5.2.3
    Test Identification CAPI.os/xcurses/all all
    Problem Summary PG4U.00188 The xcurses tests are all Unresolved if $TET_EXECUTE is too long.
    Problem Text
    Due to the amount of text, output from all assertions is not included.

    The problem is that in SRC/common/capi_curses/vt.c and
    SRC/common/capi_xcurses/vt.c:

    static char env_path[80];

    int avsstart_term(i,o,ti,to)
    FILE **i, **o, **ti, **to;
    {
    vsu_debug_enter("capi_curses/vt.c:avsstart_term()", 0);

    tet_infoline("PREP: Set environment variables and open terminal connecti
    on");
    /* set to default screen size */
    old_terminfo=getenv("TERMINFO");
    sprintf(env_path,"TERMINFO=%s%s",getenv("TET_EXECUTE"), TERMINFO);
    s2 = putenv(env_path);

    The fixed length array env_path[80] can be corrupted if the path to
    TESTROOT is long enough. This causes a call to open() to fail
    when it is passed the file name which has exceeded the array length
    and had the end clobbered, which results in the unresolved test
    result.

    The env_path[] should either be a dynamically sized array or should
    be made sufficiently large such that the array boundary is not
    exceeded by the pathname.

    Test Output
    All xcurses tests have the same unresolved result as shown below:

    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    A TSD cannot be issued for this test suite fault, as there are far too
    many tests affected. It is recommended that this request is refused.

    There is an obvious work-around for the problem: choose a location
    for the TESTROOT directory with a short enough pathname. If for
    some reason it is not possible to use this work-around, then a
    patch for the test suite should be issued.
