Details

As written in the advisory (Markdown source, shown as plain text).

### 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:[email protected]?join) * Email the maintainer [Jonas Schäfer](mailto:[email protected])
