Comment 6 Huzaifa S. Sidhpurwala 2020-03-09 03:26:14 UTC 
Mitigation:

Since the only affected code in this flaw is g_markup_parse_context_end_parse(), any application (compiled with glib2) which does not use this function or any other function which calls this vulnerable code, is not affected by this flaw.
