libexpat released a new version 2.2.2 which seems to contain 2 or 3 security fixes. I'm not sure that Python is affected by these bugs.

https://github.com/libexpat/libexpat/blob/R_2_2_2/expat/Changes#L5

Release 2.2.2 Wed July 12 2017
        Security fixes:
             #43  Protect against compilation without any source of high
                    quality entropy enabled, e.g. with CMake build system;
                    commit ff0207e6076e9828e536b8d9cd45c9c92069b895
             #60  Windows with _UNICODE:
                    Unintended use of LoadLibraryW with a non-wide string
                    resulted in failure to load advapi32.dll and degradation
                    in quality of used entropy when compiled with _UNICODE for
                    Windows; you can launch existing binaries with
                    EXPAT_ENTROPY_DEBUG=1 in the environment to inspect the
                    quality of entropy used during runtime; commits
                    * 95b95032f907ef1cd17ee7a9a1768010a825d61d

   [MOX-006]      Fix non-NULL parser parameter validation in XML_Parse;
                    resulted in NULL dereference, previously;
                    commit ac256dafdffc9622ab0dc2c62fcecb0dfcfa71fe

        Bug fixes:

                    with multipe CMakeLists.txt files
             #72  CMake: Resolve mistaken executable permissions
             #76  Address compile warning with -DNDEBUG (not recommended!)
