Possible remote Denial of Service or Data Injection.
Patches are available in https://github.com/horazont/aioxmpp/pull/268. They have been backported to the 0.10 release series and 0.10.3 is the first release to contain the fix.
To make the bug exploitable, an error suppressing xso_error_handler is required. By not using xso_error_handlers or not using the suppression function, the vulnerability can be mitigated completely (to our knowledge).
