   libX11: update to 1.6.10

   Heap corruption in the X input method client in libX11
   ======================================================

   CVE-2020-14344

   The X Input Method (XIM) client implementation in libX11 has some
   integer overflows and signed/unsigned comparison issues that can lead
   to heap corruption when handling malformed messages from an input
   method.

   Patches
   =======

   Patches for these issues have been commited to the libX11 git repository.
   libX11 1.6.10 will be released shortly and will include those patches.

   https://gitlab.freedesktop.org/xorg/lib/libx11

   commit 1703b9f3435079d3c6021e1ee2ec34fd4978103d (HEAD -> master)

       Change the data_len parameter of _XimAttributeToValue() to CARD16

       It's coming from a length in the protocol (unsigned) and passed
       to functions that expect unsigned int parameters (_XCopyToArg()
       and memcpy()).

   commit 1a566c9e00e5f35c1f9e7f3d741a02e5170852b2

       Zero out buffers in functions

       It looks like uninitialized stack or heap memory can leak
       out via padding bytes.

   commit 2fcfcc49f3b1be854bb9085993a01d17c62acf60

       Fix more unchecked lengths

   commit 388b303c62aa35a245f1704211a023440ad2c488

       fix integer overflows in _XimAttributeToValue()

   commit 0e6561efcfaa0ae7b5c74eac7e064b76d687544e

       Fix signed length values in _XimGetAttributeID()

       The lengths are unsigned according to the specification. Passing
       negative values can lead to data corruption.
