{"id":"UBUNTU-CVE-2023-46137","details":"Twisted is an event-based framework for internet applications. Prior to version 23.10.0rc1, when sending multiple HTTP requests in one TCP packet, twisted.web will process the requests asynchronously without guaranteeing the response order. If one of the endpoints is controlled by an attacker, the attacker can delay the response on purpose to manipulate the response of the second request when a victim launched two requests using HTTP pipeline. Version 23.10.0rc1 contains a patch for this issue.","modified":"2026-02-04T04:37:02.840313Z","published":"2023-10-25T21:15:00Z","related":["USN-6575-1"],"upstream":["CVE-2023-46137"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-46137"},{"type":"REPORT","url":"https://github.com/twisted/twisted/security/advisories/GHSA-xc8x-vp79-p3wm"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6575-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-46137"}],"affected":[{"package":{"name":"twisted","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/twisted@13.2.0-1ubuntu1.2+esm3?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["13.0.0-1ubuntu1","13.2.0-1ubuntu1","13.2.0-1ubuntu1.2","13.2.0-1ubuntu1.2+esm1","13.2.0-1ubuntu1.2+esm2","13.2.0-1ubuntu1.2+esm3"],"ecosystem_specific":{"binaries":[{"binary_name":"python-twisted","binary_version":"13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-bin","binary_version":"13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-conch","binary_version":"1:13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-core","binary_version":"13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-lore","binary_version":"13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-mail","binary_version":"13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-names","binary_version":"13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-news","binary_version":"13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-runner","binary_version":"13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-web","binary_version":"13.2.0-1ubuntu1.2+esm3"},{"binary_name":"python-twisted-words","binary_version":"13.2.0-1ubuntu1.2+esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46137.json"}},{"package":{"name":"twisted","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/twisted@16.0.0-1ubuntu0.4+esm2?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["15.2.1-1ubuntu2","15.5.0-1","15.5.0-2","15.5.0-2ubuntu1","15.5.0-4","16.0.0~pre1-1","16.0.0~pre1-1ubuntu1","16.0.0~pre1-2ubuntu1","16.0.0~pre1-3","16.0.0-1","16.0.0-1ubuntu0.2","16.0.0-1ubuntu0.4","16.0.0-1ubuntu0.4+esm1","16.0.0-1ubuntu0.4+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"python-twisted","binary_version":"16.0.0-1ubuntu0.4+esm2"},{"binary_name":"python-twisted-bin","binary_version":"16.0.0-1ubuntu0.4+esm2"},{"binary_name":"python-twisted-conch","binary_version":"1:16.0.0-1ubuntu0.4+esm2"},{"binary_name":"python-twisted-core","binary_version":"16.0.0-1ubuntu0.4+esm2"},{"binary_name":"python-twisted-mail","binary_version":"16.0.0-1ubuntu0.4+esm2"},{"binary_version":"16.0.0-1ubuntu0.4+esm2","binary_name":"python-twisted-names"},{"binary_name":"python-twisted-news","binary_version":"16.0.0-1ubuntu0.4+esm2"},{"binary_name":"python-twisted-runner","binary_version":"16.0.0-1ubuntu0.4+esm2"},{"binary_name":"python-twisted-web","binary_version":"16.0.0-1ubuntu0.4+esm2"},{"binary_name":"python-twisted-words","binary_version":"16.0.0-1ubuntu0.4+esm2"},{"binary_name":"python3-twisted","binary_version":"16.0.0-1ubuntu0.4+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46137.json"}},{"package":{"name":"twisted","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/twisted@17.9.0-2ubuntu0.3+esm2?arch=source&distro=esm-infra/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["16.6.0-2ubuntu3","17.9.0-1","17.9.0-2","17.9.0-2ubuntu0.1","17.9.0-2ubuntu0.3","17.9.0-2ubuntu0.3+esm1","17.9.0-2ubuntu0.3+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"python-twisted","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python-twisted-bin","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python-twisted-conch","binary_version":"1:17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python-twisted-core","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python-twisted-mail","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python-twisted-names","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python-twisted-news","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python-twisted-runner","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python-twisted-web","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python-twisted-words","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python3-twisted","binary_version":"17.9.0-2ubuntu0.3+esm2"},{"binary_name":"python3-twisted-bin","binary_version":"17.9.0-2ubuntu0.3+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46137.json"}},{"package":{"name":"twisted","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb
