- Impact Possible remote Denial of Service or Data Injection. Patches 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. Workarounds To make the bug exploitable, an error suppressing xsoerrorhandler is required. By not using xsoerrorhandlers or not using the suppression function, the vulnerability can be mitigated completely (to our knowledge).
