GHSA-6M9G-JR8C-CQW3
Vulnerability from github – Published: 2020-04-29 17:12 – Updated: 2024-09-04 19:55Impact
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
