They have been backported to the 0.10 release series and 0.10.3 is the first release to contain the fix.\n\n### Workarounds\nTo 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).\n\n### References\nThe pull request contains a detailed description: https://github.com/horazont/aioxmpp/pull/268\n\n### For more information\nIf you have any questions or comments about this advisory:\n* [Join our chat](xmpp:aioxmpp@conference.zombofant.net?join)\n* Email the maintainer [Jonas Schäfer](mailto:jonas@wielicki.name)","published":"2019-02-04T21:29:00.877Z","modified":"2026-10-20T10:50:34.544901387Z","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"PyPI","name":"aioxmpp","fixedVersion":"0.10.3"}],"fix":{"url":"https://github.com/horazont/aioxmpp/pull/268","label":"horazont/aioxmpp#268"},"references":[{"type":"FIX","url":"https://github.com/horazont/aioxmpp/pull/268"},{"type":"WEB","url":"https://github.com/horazont/aioxmpp/security/advisories/GHSA-6m9g-jr8c-cqw3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-1000007"},{"type":"WEB","url":"https://github.com/horazont/aioxmpp/commit/29ff0838a40f58efe30a4bbcea95aa8dab7da475"},{"type":"WEB","url":"https://github.com/horazont/aioxmpp/commit/f151f920f439d97d4103fc11057ed6dc34fe98be"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-6m9g-jr8c-cqw3"},{"type":"PACKAGE","url":"https://github.com/horazont/aioxmpp"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/aioxmpp/PYSEC-2019-1.yaml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-20T10:50:34.544901387Z"}}
