aioxmpp version 0.10.2 and earlier contains a Improper Handling of Structural Elements vulnerability in Stanza Parser, rollback during error processing, aioxmpp.xso.model.guard function that can result in Denial of Service, Other. This attack appears to be exploitable via Remote. A crafted stanza can be sent to an application which uses the vulnerable components to either inject data in a different context or cause the application to reconnect (potentially losing data). This vulnerability appears to have been fixed in 0.10.3.

    ### 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 ``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). ### References The pull request contains a detailed description: https://github.com/horazont/aioxmpp/pull/268 ### For more information If you have any questions or comments about this advisory: * [Join our chat](xmpp:aioxmpp@conference.zombofant.net?join) * Email the maintainer [Jonas Schäfer](mailto:jonas@wielicki.name)
