COMMAND

    Xprt

SYSTEMS AFFECTED

    X11R6 (pp3)

PROBLEM

    Paolo Molaro found following.  There is a buffer overflow in the
    postscript backend of the Xprint server: look at the S_OutStr()
    function in the file psout.c.  A user-supplied variable-lenght
    string is stored in a 512 sized buffer.  This bug is present in
    version R6, public-patch-3 and later.

SOLUTION

    Workaround should be not to run  the Xprt server.  Fix is  to make
    the function malloc() a buffer big enough and recompile.   xfree86
    and opengroup have been notified a while ago.
